Conversion Formula

mg/h = kg/h × 1000000

About Kilograms per hour

The kilogram per hour (kg/h) equals 1/3600 kg/s ≈ 2.778×10⁻⁴ kg/s, the dominant metric unit in the chemical and petrochemical industry for equipment sizing. Distillation column feed rates, reactor throughputs, heat-exchanger duty calculations, and pump datasheets routinely use kg/h. A 500 MW coal-fired power station burns ≈180 000 kg/h of coal. 1 kg/h ≈ 2.778×10⁻⁴ kg/s = 2.205 lb/h.

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.
