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 hundredweights per day

The long hundredweight per day (cwt/d, UK) equals 50.80234544/86400 ≈ 5.880×10⁻⁴ kg/s, encountered in legacy British industrial reports for colliery output, port-handling capacity, and sugar-refinery throughput. Historical British coal-mine productivity was routinely expressed in long cwt per miner per day. 1 long cwt/d ≈ 5.880×10⁻⁴ kg/s = 112 lb/d.
