Convert Micromoles per hour to Femtomoles per second
Convert Micromoles per hour (µmol/h) to Femtomoles per second (fmol/s) instantly and accurately.
Conversion Formula
fmol/s = µmol/h × 277777.7778
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 Femtomoles per second
The femtomole per second (fmol/s) equals 10⁻¹⁵ mol/s, the detection threshold of ultra-sensitive bioanalytical instruments. Modern nano-HPLC-MS systems and chip-based microfluidic biosensors detect enzyme reaction rates and protein-ligand binding kinetics at fmol/s throughput. Single-molecule fluorescence assays and electrochemical biosensors for early cancer biomarkers routinely operate at 0.1-10 fmol/s. 1 fmol/s = 10⁻¹⁵ mol/s = 60 fmol/min.
