Conversion Formula
kg/s = gr/h × 1.799969722e-8
About Grains per hour
The grain per hour (gr/h) equals 6.479891×10⁻⁵/3600 ≈ 1.800×10⁻⁸ kg/s, used in HVAC psychrometric calculations for dehumidifier capacity and moisture-removal rates. ASHRAE load calculation spreadsheets report latent loads in grains of water per hour; a typical residential dehumidifier removes 5×10⁵-2×10⁶ gr/h. 1 gr/h ≈ 1.800×10⁻⁸ kg/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.
