Conversion Formula

nmol/s = µmol/h × 0.2777777778

About Micromoles per hour

The micromole per hour (µmol/h) equals 10⁻⁶/3600 ≈ 2.778×10⁻¹⁰ mol/s, used for photosynthesis gas-exchange measurements, soil respiration CO₂ efflux, and slow metabolic pathway fluxes. Leaf gas analysers (LI-COR, WALZ) report CO₂ assimilation in µmol/h; plant root nutrient uptake studies use µmol/h/g fresh weight. 1 µmol/h ≈ 2.778×10⁻¹⁰ mol/s.

About Nanomoles per second

The nanomole per second (nmol/s) equals 10⁻⁹ mol/s, the scale of moderate laboratory flow reactions and microreactors in pharmaceutical synthesis. A micro-HPLC column handling a 1 μM analyte at 1 mL/min delivers ≈16.7 nmol/s; continuous-flow photochemistry reactors in API synthesis routinely reach 10-100 nmol/s throughput. 1 nmol/s = 10⁻⁹ mol/s = 60 nmol/min.
