Lux to micromoles per square meter per second
Type a value in lx to get it in µmol/m²/s instantly.
Nothing on our list is smaller: office lighting is 1.35× brighter. Over a 12-hour day that is a light integral of about 0.32 mol/m².
Convert the other way: µmol/m²/s to lx
What it means
How much light is that?
Lux and PPFD relate differently for every light source, because lux weights by the human eye. The 54 lux per µmol used here is the daylight figure; a red-heavy LED can be half that.
The math
How to convert lx to µmol/m²/s
To convert lux to micromoles per square meter per second, multiply by 0.0185185.
Example: 400 lx × 0.0185185 = 7.40741 µmol/m²/s.
In the other direction, 1 µmol/m²/s = 54 lx.
