Common Ratios

List of common ratios between machines to produce various products optimally (without stalling)
For example: To make "rails", the right ratio is 1 "iron stick" assembler feeding 2 "rail" assemblers.
If there is no machine mixing (assemblers/chemical plants/furnaces) then ratios stay the same between assembly tiers.

A Rocket needs 100 Rocket Parts.
To get Space Science (no productivity modules in the silo);
a rocket needs 1000 (100*10) of each component of the rocket part + the requirements for the satellite.
This is a ratio of (1100i * 10s) : (1050i * 15s) : (1100i * 15s) = 11000 : 15750 : 11000 or if divided by 250 then simplified to 44 : 63 : 44.
Where 20s and 30s are the respective crafting speeds of recipes.
Note: This produces 2.5 science/min, however the silo is capable of 2.9 science/min
Module Ratio is approximate with lvl 3 productivity modules and lvl 1 speed modules in 1 beacon then silo is capable of 3.9 science/min

Belts

See Belt Transport System for all relevant belt information.

Transport Belt Throughput - Items per second (i/s) passed over one belt tile.
Transport Belt Density - Maximum items that fit in one tile: 8 items for all belts.

	Throughput (Both Sides)	Underground Spacing
	15 i/s	4 tiles
	30 i/s	6 tiles
	45 i/s	8 tiles
	60 i/s	10 tiles

All belts can hold up to 8 items on each tile.

Its common to stack belts to form a Main Bus.
To learn more about the main bus concept, you can watch these playlists: Xterminator, JDplays and Nilaus .

Underground belts can be side loaded

Splitters can filter items

Belts can be woven

Balancers

Balancers are used to evenly distribute items over multiple belts, they are commonly used at ore patches or the Main Bus.

Balancers that are input balanced take evenly from input belts.
Balancers that are output balanced distribute evenly to output belts.
Balancers that are output balanced under back pressure, keep an even distribution even if one or more output belts are blocked.
Balancers that are throughput limited may not provide the maximum throughput due to bottlenecks.

4x4 belt balancer

Tips

Don't overuse balancers, use them when needed.
Make a build that's inherently balanced, by letting the assembly machines consume a full belt of items.
Balancers can still be useful regardless; most common are the 44 and 88 throughput unlimited.
Being throughput unlimited, the input/output amount can vary, thus those two cover most cases.
There are more designs available online such as the Balancer Book by Raynquist.

Uranium Facts

Uranium processing has a 99.3% chance to produce 1 uranium-238 and a 0.7% chance to produce 1 uranium-235 from 10 ore.
It's recommended to save up 40 U-235 to kick off the Kovarex Enrichment Process in order to speed up U-235 production.

10000

993

** 10000 not 1000 ore, as Uranium processing takes 10 ore and produces 1 product on average.

Mining

Mining rate relies on drill mining speed divided by ore mining time.
See various mining arrangements with varying mining coverage.
Mining productivity research increases the output of all mining drills and pumpjacks.
Refer to kirk's calculator for more information on productivity bonuses. Note: mining productivity bonus on settings page

To mine uranium ore, you must supply the mining drill with sulfuric acid.

Per 10 uranium ore mined, 10 sulfuric acid are consumed.

Miners = Belt Throughput / (Mining Rate * Productivity)
* Assuming no mining productivity bonus

Tip: Mining drills will output resources directly without the need of inserters.

Science

Research is balanced in the number of different science packs required, so optimally all science should be produced at the same rate.
Science Packs have various crafting times and outputs; you'll need different number of assemblers making each type to prevent bottlenecks.

Number of assemblers needed to produce science equally

1R/13m

75/m

45/m

1R/22m

Check the ratios for each science pack.
Check your Resource requirements to keep production steady.
You can move science packs between labs with inserters.
Launching 1-100 Space Science in a rocket will give you 1-100 Fish respectively.

Space Science

For 1 space science pack per second you need to launch a rocket with a satellite every 16.67 minutes.

Rockets launch interval (in minutes) = (1000 science / (assembler speed * ratio multiplier)) * (1min/60sec)

During the day, excess power generated is stored in accumulators, during the night, accumulators release their charge to power your factory.
As Needed a.k.a YOLO placement:
- Place accumulators until they can keep your factory powered through the night.
- Add some extra accumulators to account for burst consumption, such as firing a lot of lasers.
- Then place solar panels until those accumulators are fully charged by the end of the day.

Summary

One uranium fuel cell will always last 200 sec, even if the produced heat does not get consumed, so the rest of the energy is wasted if not used.
To prevent energy waste, unused energy could be buffered and the nuclear reactor setup switched off before the energy buffer, such as steam tanks or accumulators, are full.
A nuclear reactor buffers 500 °C worth of energy after it fully heated up. Heat pipes, steam pipes and heat exchangers also buffer energy.
A Storage tank holding 25k units of Steam at 500 °C contains 2.425 GJ of energy, which is equal to 485 fully charged Accumulators!
Reactors experience a 100% increase in energy output when placed directly next to another reactor.
One Offshore pump can fully supply 116.5 Heat Exchangers driving 200 Steam Turbines producing 1160 MW .

You will need 1 centrifuge to produce U-235 to make fuel for 1 Reactor continuously.
3 uranium ore miners will sustain production.

It takes 1 U-235 and 19 U-238 to create 10 fuel cells, but you can reprocess 10 used up uranium fuel cells to get 6 U-238, which results in a ratio of 13 U-238 to 1 U-235.

When starting oil, it is beneficial to rush Advanced Oil Processing research.
This unlocks Light/Heavy Oil, and enables more efficient oil processes by converting the Light and Heavy Oil into Petroleum Gas.

Advanced Oil

Simple Cracking Ratio

Accurate Cracking Ratio

Moduled Cracking Ratio *

If you want to convert all refinery products to petroleum: for every 20 refineries you have running Advanced Oil Processing, you need 5 chemical plants cracking heavy oil into light oil and 17 chemical plants cracking light oil into petroleum.

This YouTube video for the 0.16 version of Factorio, that explains the setup and calculations in detail. The ratios have changed but the concept and build style are still relevant.

You can supply ~106 refineries + respective cracking from 1 pipeline at 1200 oil/s.
You can supply ~23 moduled refineries + respective cracking from 1 pipeline at 1200 oil/s.

Default water input for Refineries is after Oil going clockwise.
Default water input for Chemical Plants is the opposite.
The inputs can be flipped with H or V

Caution: If you use the original spreadsheet as is, it will not produce correct results for version v2.0.7. You would need to make the same modifications to get the same results.
Also double checked with kirk's calculator for standard and moduled oil ratios.

Fluid Wagon Transfer

Fluid wagons require at least one pump and at most 3 pumps per fluid wagon.
If more than 3 pumps can be active on the fluid wagon, only 3 will “latch on” and be in use with the remaining pumps inactive.
Pumps and Storage Tanks have a maximum throughput of 1,200 fluid/s.
Pipelines are limited to a 320x320 area before needing a pump
Using underground pipes counts as less entities then if straight pipe for same distance.
Fluid wagons can hold 50,000 units of fluids which is equal to 2 Storage Tanks.

Cargo Wagon Transfer

The table shows how long it takes to load, or unload, chests to a Cargo Wagon. The transfer times shown are for 6 fast (or stack inserters) to 1 wagon. If you use 12 fast (or stack inserters), the transfer time is halved. The table ignores Inserter capacity bonus (research).

Cargo Loading Setup

Notes:

The transfer times listed are worse than the real transfer times! This is because inserters grab the next item(s) from the chest after a wagon leaves. When the next wagon arrives, the inserter already did the first swing (to load, or unload).
The times shown are for wagon to chest, or chest to wagon. Transferring from belt to wagon, or wagon to belt is slower.
* The barrel transfer rate does not increase when you unlock 12 items per swing, because inserters can only move a full stack (10).

The next table shows how much would chests fill up with the contents of a fully loaded cargo wagon.
Numbers showing resulting items in each chest, and numbers in [brackets] take those rounded up to the nearest stack size.

Items per chest from 1 cargo wagon's worth
Chests per wagon	Slots per chest	10 items per stack	50 items per stack	100 items per stack	200 items per stack
12	3.3 [4]	34i [40i]	167i [200i]	334i [400i]	667i [800i]
6	6.7 [7]	67i [70i]	334i [350i]	667i [700i]	1,334i [1,400i]
3	13.3 [14]	134i [140i]	667i [700i]	1,334i [1,400i]	2,667i [2,800i]

Notes:

Cargo wagon slots can be filtered with MMB and limited just like a chest.
Cargo wagon configuration can be copied with Shift+RMB/Shift+LMB on wagon, as well as on individual slots.

Inserter Throughput

Inserter Throughput - Items per second (i/s) moved by the inserter between targets (chests, belts, assemblers, trains, etc...)
Inserter capacity research is used to increase the throughput.

The inserter throughput displayed in the tables below can be used to calculate the exact number of inserters needed for your task.
Inserters Required = (Target Item Rate) / (Inserter Throughput)

Inserter Throughput (i/s)
Inserter Bonus Level
Stack Size
3	1.80 i/s	1.67 i/s	1.73 i/s	1.76 i/s
3	2.50 i/s	2.25 i/s	2.37 i/s	2.43 i/s
3	3.60 i/s	3.10 i/s	3.33 i/s	3.46 i/s
3	6.92 i/s	5.29 i/s	6.00 i/s	6.43 i/s
12	27.69 i/s	6.79 i/s	10.91 i/s	13.85 i/s

Taking items from belts is slightly slower than placing them.
It takes 1.625 stack inserters (exclusive swinging time) to fill half a blue belt.
As always check the Wiki for more in depth information.

Inserter Capacity Bonus

Inserter capacity research is used to increase the stack size of the inserters.

The bonus is more effective when moving from stack to stack (chests, wagons, machines) than when moving from stack to belt or belt to stack as inserters must wait to collect a full stack from a belt, but can instantly grab a stack from containers.

Grabbed Items

	1 (base)	2 (base)	6 (base)
1		3 (+1)	7 (+1)
2	2 (+1)	4 (+1)	8 (+1)
3		5 (+1)	9 (+1)

Modules and Beacons

Modules allow to change how fast, efficient, or productive your machines are working.
Beware of Diminishing Returns with beacons and with productivity.
Also see Beacon Arrangement Power Efficiency.
Having faster machines with Speed Modules means you'll need less to fill a belt than you did before.
- While generally space is infinite, this becomes very useful in bot networks to minimize flight distance.
- You can also speed up Pumpjacks to counteract the diminishing yields on patches, or Mining Drills to speed up patch depletion.
- Speed Modules increase the energy consumption especially with beacons so be wary.
Putting Productivity Modules in your machines means you'll use less raw resources.
- This is absolutely critical for late game with big factories, especially when doing infinite research.
- Be wary, Productivity Modules increase the energy consumption and pollution, while decreasing machine speed.
- Use speed moduled beacons to compensate for the speed penalty.
Efficiency Modules reduce power usage.
- Best to put in energy hogs.
- Reducing Energy = Reducing pollution
- Tier 1 are superb in mining drills. Because you'll have lots of mining drills, you can save a lot of energy.
Quality Modules increase the change to get higher quality items (SA only).
- Speed modules counteract this effect so do no mix or use "speed beacons"
- Use quality machines to save on space esp useful on space platforms

Vehicle Fuel Bonus

Fuel affects train max speed and how fast trains accelerate.
The braking force research affects how fast trains slow down.
The faster a train can slow down, the longer it can stay at higher speeds.
A single locomotive can go 31,176.5 blocks on 1 rocket fuel.

Space Platforms

Starting planet (Nauvis) has no asteroids to worry about, so orbital platforms do not need defenses
You can connect asteroid collectors to circuit network to set filters on what they can grab so you don't overflow on material
The inner planet space has medium asteroids that needs shooting apart.

Use robots (vs mining by hand) to gather rocks to get tungsten ore easily before getting access to patches
Rush the Foundry asap and set it as the building to build more Foundries; because it includes built in productivity, you will get a free Foundry for every 2 crafts!
You can use inserters to dump (destroy) items into lava (like excess stone).
1 ore = 15 molten fluid

Space is can be limited, and scrap recycling yield a lot of products, thus using robots can be very convenient to sort everything out, and craft starter items
Setup filters on

Use to process recycling

Recycling

Recycler Scrap Percent Chance Ratios

20%

Items that have no recipe (ores, etc..) cannot be recycled
Items that have irreversible recipe (smelted, etc..) will have a 75% chance of being destroyed
The time it takes to recycle an item is 1/16th (0.0625) of the time it takes to craft that item multiplied by recycler crafting speed.
Recycler (non moduled) takes in 2.5 scrap/s and spits out 1.47 items/s

Base Resources Conversion

How many Recyclers are needed to work with belts of scrap and its outputs

Consume Scrap	6	12	18	24
Produce Items	10	20	30	40

Shortcuts (Most Used)

Alt - reveal detailed information on entities, you can also use the shortcut bar (click on the ALT button).
MMB - clear an item in the quick bar, and can set filters in cargo wagons and your inventory. (CMD+RMB on macOS)
R - rotate entities, even when already placed, Shift+R for the opposite.
CTRL-LMB - Put/Take All Items, CTRL-RMB - Put/Take Half Items.
Z Drop 1 Item (can do it directly into machines)
F Pick up items from ground
Hold Shift while building to place a ghost of the item (single entity blueprint).
Shift+RMB will copy entity configurations, Shift+LMB will paste them.
- This works for: filter inserters, assemblers, requester chests, combinators, etc...
- You can paste across multiple entities by dragging.
- You can copy from assemblers into requester chests (requests the required amount to craft 30 seconds worth of the item production).
- You can copy individual slots (inventory, cargo wagon).
Q while hovering over anything to quick-select it from your inventory.
- Press Q on ores to select miners.
CTRL+C, CTRL+V, CTRL+X, CTRL+Z, CTRL+Y - copy, paste, cut, undo and redo your builds. (CMD vs CTRL on macOS.)
Numpad- / Numpad+ - increase / decrease the size of any placed tile (such as landfill or concrete).
Shift+RMB - clear Blueprint or Deconstruction Planner Filters.
Shift+LMB - ping the ground/map.
` (tilde key) - Open chat/command line.

Commands (These do not disable achievements)

/permissions, disable Craft - Useful for Lazy Bastard Achievement .
/screenshot [x resolution] [y resolution] [zoom] - Useful for large/HD screenshots.
(Resolution is optional and defaults to the current window size and zoom is optional and defaults to 1).
[item=iron-plate] / [fluid=crude-oil] - part of Rich text, will display as an icon! Useful for blueprints/station names.
To quickly get a rich text tag for an item: open the console, then Shift+LMB on the item (eg. in your inventory, a chest, etc.)
A rich text tag for that item appears in the console and can be copied.

Debug Menu (`F4` also `F5` )

Some useful options to enable:

show-fps - FPS/UPS
show-multiplayer-statistics - Latency
show-tile-grid, show-raw-tile-transitions - Precision construction
show-rail-paths - Less likely to get run over
show-transport-line-gaps - Identify unsaturated belts
show-player-robots - Makes it clear if there are stragglers
allow-increased-zoom

Misc

Combat : Weapon Range Comparison Diagram.
Inserters will always place items on the furthest side of the belt, and prioritize taking items from the closest.
Placing over ghosts will preserve the recipes.
Fluids can move through boilers, tanks, and electric mining drills (only when mining uranium).
Blueprints can be used from map view.
