'''Labs''' are buildings that perform [[research]] for [[technologies]] by consuming [[science pack]]s. Use of a lab is required to progress in Factorio.<br />
<br />
The player can only research one technology at a time, but can use multiple labs for faster results. The speed bonus of labs when [[Lab research speed (research)|Lab research speed]] is researched and modules are present can be calculated using this formula: <code>research_bonus * module_bonus = speed_bonus</code>; the percentage bonuses have to be converted to decimals (e.g. +140% = 2.4) before the formula is used.<br />
<br />
When [[productivity module]]s are used in labs, the productivity bonus is directly calculated and applied each [[game-tick|tick]] so the productivity bar is simply cosmetic. This means that it does not matter that the productivity bar resets when the research is changed, no productivity bonus is lost. [https://forums.factorio.com/26860]<br />

==Production requirements==<br />
Calculating the number of science packs needed per second is straightforward:<br />
* <code>Adjusted Cycle Time = <in-game Cycle Time> /((<in-game Lab Research Speed> / 100) + 1)</code><br />
* <code>Packs per Second = 1 / (Adjusted Cycle Time / <# of labs>)</code><br />
<br />
Thus, for a 10 lab setup, researching Nuclear Power (30 second cycle time) with Lab Research Speed 4 (140% bonus), the math would be:<br />
* ACT = 30 / ((140 / 100) + 1)<br />
**= 12.5 seconds, adjusted cycle time<br />
* PPS = 1 / (12.5 / 10)<br />
**= 0.8 Science per second<br />
<br />
This means 0.8 science packs per second, of each type, would need to be produced to continuously supply the labs.<br />
