Micromoles per square meter per second to lux

Type a value in µmol/m²/s to get it in lx instantly.

21,600lx

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.

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 lx

To convert micromoles per square meter per second to lux, multiply by 54.

Example: 400 µmol/m²/s × 54 = 21,600 lx.

In the other direction, 1 lx = 0.0185185 µmol/m²/s.
