Convert Milligrams per hour to Kilograms per second
Convert Milligrams per hour (mg/h) to Kilograms per second (kg/s) instantly and accurately.
Conversion Formula
kg/s = mg/h × 2.777777778e-10
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 Kilograms per second
The kilogram per second (kg/s) is the SI coherent derived unit of mass flow rate relevant across all branches of engineering. Jet turbofan engines pass 100-800 kg/s of air through the core and bypass duct combined; drinking-water intake pipelines for a city of one million people sustain flow rates of 1 000-4 000 kg/s. It is the reference unit in the continuity equation and mass-conservation calculations. 1 kg/s = 3 600 kg/h ≈ 2.205 lb/s.
