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 Long tons per second
The long ton per second (long ton/s) equals 1 016.0469088 kg/s, based on the UK long ton of 2 240 lb used historically in British heavy industry and naval engineering. It quantifies extremely high discharge rates such as large dam break surges or catastrophic industrial spillages. 1 long ton/s = 1 016.0469088 kg/s ≈ 1.016 t/s ≈ 1.120 short ton/s.
