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 second

The short ton per second (ton/s, US) equals 907.18474 kg/s, used for the very highest industrial and military throughput rates. The Space Shuttle Main Engine consumed propellant at ≈480 kg/s LOX + 160 kg/s LH2 ≈ 640 kg/s ≈ 0.71 ton/s; a large blast-furnace tap discharges molten iron at 1-3 ton/s. 1 short ton/s = 907.18474 kg/s = 2 000 lb/s.
