Convert Milligrams per hour to Micrograms per second
Convert Milligrams per hour (mg/h) to Micrograms per second (µg/s) instantly and accurately.
Conversion Formula
µg/s = mg/h × 0.2777777778
About Milligrams per hour
The milligram per hour (mg/h) equals 10⁻⁶/3600 ≈ 2.778×10⁻¹⁰ kg/s, adopted in transdermal drug-patch pharmacokinetics to express dermal absorption rate. A nicotine patch typically releases 14-21 mg over 24 h, corresponding to ≈0.58-0.88 mg/h. Environmental emission tests for laboratory fume hoods also express contaminant escape in mg/h. 1 mg/h = 1/3600 mg/s.
About Micrograms per second
The microgram per second (µg/s) equals 10⁻⁹ kg/s, the working unit for ultra-trace flow measurements. HPLC pumps delivering isotopic tracers, or nanoliter dispense systems in drug-discovery robotics, operate at µg/s throughput. A 1 µl/min water stream at 1 g/cm³ corresponds to ≈16.7 µg/s. 1 µg/s = 10⁻⁹ kg/s = 60 µg/min.
