millimole per square meter second

Photon flux densityexact by definition

The millimole per square metre per second is 10⁻³ mol/(m²·s), exact by prefix, and equals 1000 μmol/(m²·s). It is rarely used, since full sunlight is only about 2 mmol/(m²·s) and the resulting figures lose useful resolution.
