Convert Grams per hour to Kilograms per hour
Convert Grams per hour (g/h) to Kilograms per hour (kg/h) instantly and accurately.
Conversion Formula
kg/h = g/h × 0.001
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 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.
