Convert Picomoles per hour to Micromoles per second
Convert Picomoles per hour (pmol/h) to Micromoles per second (µmol/s) instantly and accurately.
Conversion Formula
µmol/s = pmol/h × 2.777777778e-10
About Picomoles per hour
The picomole per hour (pmol/h) equals 10⁻¹²/3600 ≈ 2.778×10⁻¹⁶ mol/s, used in dermal permeability studies and slow-release pharmaceutical patch bioavailability tests. Passive diffusion of steroid hormones through biological membranes is quantified at pmol/h per cm² of membrane area. 1 pmol/h ≈ 2.778×10⁻¹⁶ 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.
