Micromoles per square meter per second to daily light integral, 12 hours
Type a value in µmol/m²/s to get it in mol/m²/day instantly.
That's 1.33× as bright as seedlings under lights, while a flowering crop is 2× brighter. Over a 12-hour day that is a light integral of about 17.28 mol/m².
Convert the other way: mol/m²/day to µmol/m²/s
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 µmol/m²/s to mol/m²/day
To convert micromoles per square meter per second to daily light integral, 12 hours, multiply by 0.0432.
Example: 400 µmol/m²/s × 0.0432 = 17.28 mol/m²/day.
In the other direction, 1 mol/m²/day = 23.1481 µmol/m²/s.
