Convert Femtomoles per hour to Micromoles per second
Convert Femtomoles per hour (fmol/h) to Micromoles per second (µmol/s) instantly and accurately.
Conversion Formula
µmol/s = fmol/h × 2.777777778e-13
About Femtomoles per hour
The femtomole per hour (fmol/h) equals 10⁻¹⁵/3600 ≈ 2.778×10⁻¹⁹ mol/s, used in slow biological transport studies such as steroid diffusion across lipid bilayers or mineralisation reactions in nanotribology experiments. Passive permeation tests for drug molecules across synthetic membranes reach detection at fmol/h. 1 fmol/h ≈ 2.778×10⁻¹⁹ mol/s.
About Micromoles per second
The micromole per second (µmol/s) equals 10⁻⁶ mol/s and is numerically equal to the katal (kat) - the SI unit of catalytic activity. One katal of enzyme converts exactly 1 µmol of substrate per second; preparative HPLC columns and benchtop continuous-flow synthesis reactors commonly operate at µmol/s throughput. 1 µmol/s = 1 µkat = 10⁻⁶ mol/s = 60 µmol/min.
