Your inputs
Change any value to update the result instantly.
Daily light integral
23.04 mol/m²/day
PPFD
400 µmol/m²/s
Photoperiod
16 hr
Total photons per day
2,30,40,000 µmol/m²/day
Formula and working
DLI (mol/m²/day) = PPFD (µmol/m²/s) × photoperiod (hr) × 3600 ÷ 1,000,000
- 1
Collect the inputs
PPFD = 400 µmol/m²/s; Photoperiod = 16 hr
- 2
Apply the formula
DLI (mol/m²/day) = PPFD (µmol/m²/s) × photoperiod (hr) × 3600 ÷ 1,000,000
- 3
Result
Daily light integral = 23.04 mol/m²/day
