Micromoles per hour (µmol/h)
Picomoles per day (pmol/d)

Conversion Formula

pmol/d = µmol/h × 24000000

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 Picomoles per day

The picomole per day (pmol/d) equals 10⁻¹²/86400 ≈ 1.157×10⁻¹⁷ mol/s, applied in clinical biomarker assays for trace hormones and in isotope-dilution pharmacokinetics. Testosterone circulating at very low concentrations (< 5 pmol/L) with a plasma clearance of 5 L/d yields urinary excretion on the pmol/d scale. 1 pmol/d ≈ 1.157×10⁻¹⁷ mol/s.
