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 second

The milligram per second (mg/s) equals 10⁻⁶ kg/s, common in pharmaceutical tablet coating lines and laboratory syringe pump calibrations. A modern inkjet printhead deposits ink at roughly 1-10 mg/s per nozzle row during high-speed printing; medical infusion pumps are calibrated to this scale for drug-delivery accuracy. 1 mg/s = 10⁻⁶ kg/s = 60 mg/min.
