About Grams per hour

The gram per hour (g/h) equals 10⁻³/3600 ≈ 2.778×10⁻⁷ kg/s, used in fuel-cell hydrogen consumption tests, precision agricultural sprayers, and humidity calibration. A 1 kW PEM fuel cell consumes roughly 750 g/h of hydrogen at rated power. Automotive air-conditioning refrigerant leak standards are set in g/h. 1 g/h ≈ 2.778×10⁻⁷ kg/s = 1/3600 g/s.

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.
