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 Pounds per second
The pound per second (lb/s) equals 0.45359237 kg/s, widely used in aerospace and large industrial equipment. A Saturn V first-stage engine consumed ≈13 short tons of propellant per second, equal to ≈26 000 lb/s; a typical large centrifugal pump handling water moves ≈500-2000 lb/s at operating flow. 1 lb/s = 0.45359237 kg/s ≈ 3 600 lb/h.
