About Pounds per hour

The pound per hour (lb/h) equals 0.45359237/3600 ≈ 1.260×10⁻⁴ kg/s, the dominant unit in US process engineering and steam-boiler rating. Packaged steam boilers are rated in lb/h of steam output (typical range 100-2 000 lb/h); HVAC cooling-coil latent loads are calculated in lb/h of moisture; flue-gas emission inventories are reported in lb/h per stack. 1 lb/h ≈ 1.260×10⁻⁴ 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.
