'''Units''' - by definition - are definite, representational quantities of measurement for different systems. Units can represent the measuring of electricity, amount of items, the time taken/required to perform a task or even the amount of stacks of items with differing amounts within said stacks.

Not all in-game units are simulated with full realism.

== Power ==
Power is defined as work being done per unit of time.

=== Watt (W) ===
The basic unit of power is 1 watt (W), which is defined as '''1 W = 1 J/s ''', ie. one Joule of work being done every second.

The game commonly deals with larger units, namely kilowatts (kW) and megawatts (MW).

[[Lamp|Lamps]] use 5 kW while turned on. A [[Radar]] uses 300 kW while active - equivalent to 60 lamps.
One [[Steam engine]] is capable of outputting 900 kW.

== Work ==

Work is defined as a transfer of energy, or as energy being "spent".

=== Joule (J) ===
The basic unit of work is 1 joule (J), and is equivalent to the work done (total energy transferred) by one watt applied for one second: '''1 J = 1 W s'''.

In-game, [[Fuel]] is really just potential energy, which, when applied, does work. For example, every piece of [[coal]] burned will produce 4 MJ. One [[Accumulator]] is capable of storing 5 MJ.

In the real world, kilowatt hours is a much more common unit for energy, but it is ''not'' an [[:WIKIPEDIA:International_System_of_Units#Derived_units|SI derived unit]] so it is not used by the game.

== [[Time]] ==

=== Tick (1/60 s) ===
A 1/60 second in game. This is the shortest time fraction the game handles.

=== Second (s) ===
One second in-game. This is not guaranteed to correspond to one real second. For example, slow computers may not manage to calculate an entire tick during the corresponding real time frame of 1/60th of a second.

=== Day ===

A day is 25000 in-game ticks or 416.67 in-game seconds (= 6.94 in-game minutes) long.

== [[Map structure|Distance / Space]] ==

=== Tile ===
The tile is both used as a unit of distance/length and a unit of area. For example, the size of an object may be expressed as "2×2 tiles", which means the object covers an area of 4 square tiles or tiles². The unit of square tiles is often simplified into tiles. It can be assumed, that a tile has the length of 1 meter.

=== Chunk ===
A chunk is a quadratic area where one side is 32 tiles long. (1024 square tiles). You can view a grid of tiles and chunks in [[Debug mode]] by pressing {{keybinding|F5}}.

=== Kilometers ===
A kilometer is 1000 meters, it is used to measure distance traveled in a [[space platform]].

== Force ==

=== Newtons (N) ===
Newtons measure the amount of forceful thrust of a space platform being moved by [[thruster]]s. This can be increased by adding more thrusters. More force can add damage to [[asteroids]] colliding with a platform, but the asteroids will, in turn, damage the platform as well.

== Mass / Weight ==

=== Tons (t) ===
A single ton is 1000 kilograms. The only time mass is measured in ''Factorio'' is calculating the sum of all parts that make up a space platform. The more components added and the bigger the platform's size, the more mass it will accumulate. The larger the mass of a platform, the harder it is for thrusters to move it to its destination.

== Logistics ==

=== Throughput ===

Items per time, or fluid-units per time. A unit measurement is

items / game-minute

==== Belts ====

Throughput = speed × density

For comparison: A [[transport belt]] transports normally about 900 items per in-game minute. A [[fast transport belt]] up to 1800 items/min and [[express transport belt]] nearly 2700 items / min.
See [[Transport belts/Physics|physics of transport belts]] for more information.

==== Logistic robots ====

Throughput depends on the distance, the number of robots and their item-stacksize. Let's assume a robot can travel 1 tile per second and can transport only one item at once. It needs also to return. Then this robot can transport ½ item per second. If you use 2 you can transport 1 item per second. If you double the distance, we are again at ½ item per second.

==== Trains ====

Items per train is the sum of all wagons' capacity (40 stacks for [[cargo wagon]], 50000 fluid for [[fluid wagon]] & 100 shells for [[artillery wagon]])

Top speed (later referred to as S) and acceleration (later referred to as A) depend on fuel type and train weight, for a coal-powered single locomotive without wagons they are 72 tiles/s and 9.26 tiles/s/s.

After some threshold the top speed starts decreasing linearly as train mass increases; acceleration is proportional to amount of locomotives pointing towards the travel direction and inversely proportional to train mass; deceleration is proportional to amount of wagons + amount of locomotives, inversely proportional to train mass, and affected by [[braking force (research)]] (train mass is the sum of all wagon and locomotive masses; see detailed info on wagon masses on [[locomotive]], [[cargo wagon]], [[fluid wagon]], and [[artillery wagon]] pages).

Warning: The following calculations assume deceleration = acceleration and do not account for red lights.

Travel time is <syntaxhighlight lang="lua">(2S / A) + (distance - 4 * S^2 / A) / S</syntaxhighlight> if the stations are far enough for the train to achieve full speed. If they are closer than that, the time is <syntaxhighlight lang="lua">2 * sqrt(distance / A)</syntaxhighlight>

Since a train has to make a trip back to load, the total throughput is <syntaxhighlight lang="lua">items per train / (2 * travel time)</syntaxhighlight>

=== Capacity ===
Basically items per transport unit. This depends in many cases on the item type you use. A [[cargo wagon]] has a capacity of 40 stacks. Stack size depends on the item type so this means that it can hold 2000 items for ore, or 4000 for steel or copper plates.

=== Density ===
Measured in items per tile.

An item, that lays on ground has the size of 0.28 tiles<sup>2</sup>. On one tile we can place 12.752041 items, which means, that we can put in the best case 12 items on one tile.

==== Belts ====

For belts this is the same: We have two lanes on a belt, 4 items per lane or 8 item on one belt.

On belts there comes also another thing into play: '''Compression.''' Good compression is, when you fill a belt so, that you come to the maximum density and so to the maximum '''throughput'''.
See also [[Transport belts/Physics|physics of transport belts]] for more information.

=== Stacks/chests ===
On the first glance, it is simple: A chest has the size of one tile. You have X number of stack in a chest, where you can put Y numbers of items into each, so the density is simply X × Y.

The thing changes, if you use mods, that add chest-like transport boxes, which enables to pack/box items.

Benseer: /* "Nuclear power" achievement conditions */ new section

== "Solaris" achievement notes ==
The description for the Solaris achievement says "The electric network may not have any electricity producers besides solar panels connected to it." I'm not sure if it is entirely correct: I had backup coal power when I got that achievement, though it probably was automatically disconnected by [[power switch]]es because my batteries stopped discharging below 40%. --[[User:Evg-zhabotinsky|Evg-zhabotinsky]] ([[User talk:Evg-zhabotinsky|talk]]) 19:37, 13 December 2020 (UTC)
: The page is correct. -- [[User:Bilka|Bilka]] ([[User talk:Bilka|talk]]) - <span style="color:#FF0000">Admin</span> 15:46, 19 January 2021 (UTC)

== Map generation settings that disable achievements ==

Currently, the phrase "setting enemy bases to anything lower than default" is used in a couple of places on the page, but this phrasing is not correct. You -can- disable enemy expansion and evolution and still get all achievements. You can also disable pollution except maybe for the "it stinks" achievements which becomes impossible for technical reasons.
I'm removing the phrasing across the page, since it is misleading. --[[User:Zaz|Zaz]] ([[User talk:Zaz|talk]]) 10:09, 1 November 2024 (UTC

== The criteria for completing the DLC ==

Could someone that knows the details about what triggers "express delivery", "work around the clock", and "second star" add explanations for those under the spoiler tags? It currently just says "the criteria for completing the dlc" which is useless. I cant do it myself because i do not know and i dont want to be spoiled. --[[User:Zaz|Zaz]] ([[User talk:Zaz|talk]]) 10:33, 2 November 2024 (UTC)

== "Nuclear power" achievement conditions ==

I'm inexperienced, but looking at the lua code for it, it seems like you need to have: built a nuclear reactor, put nuclear fuel cells in a reactor, and generated power in a steam turbine, not necessarily in that order or connected. I personally got it with acid neutralization on Vulcanus. It might be good to specify this on the page. --[[User:Benseer|Benseer]] ([[User talk:Benseer|talk]]) 15:25, 16 December 2024 (UTC)
