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.
About Short tons per minute
The short ton per minute (ton/min, US) equals 907.18474/60 ≈ 15.120 kg/s, typical for high-capacity conveyor belts and bucket-wheel excavators in open-cast mining. A large surface coal mine loads unit trains with overland conveyors rated at 5 000-15 000 short ton/h = 83-250 ton/min. 1 short ton/min ≈ 15.120 kg/s = 2 000 lb/min.
