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 Kilograms per day
The kilogram per day (kg/d) equals 1/86400 ≈ 1.157×10⁻⁵ kg/s, standard in environmental engineering for pollutant load calculations and water-treatment material dosing. Activated-carbon dosing for a water-treatment plant, sludge dewatering output, and river sediment transport surveys all use kg/d. A medium river in flood may move 10 000-100 000 kg/d of suspended solids. 1 kg/d ≈ 1.157×10⁻⁵ kg/s.
