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 Metric tons per day
The metric tonne per day (t/d) equals 1 000/86400 ≈ 0.011574 kg/s, standard in hydrometallurgy, wastewater treatment, and environmental mass-balance reporting. A large copper smelter processes 2 000-3 000 t/d of ore; a modern desalination plant produces 100 000-500 000 t/d of potable water; IPCS industrial emission guidelines use t/d for stack mass rates. 1 t/d ≈ 0.011574 kg/s ≈ 1.102 short ton/d.
