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 Slugs per second
The slug per second (slug/s) equals 14.5939029372 kg/s, derived from the Imperial system where 1 slug = 1 lb·s²/ft ≈ 14.594 kg. The slug is the coherent mass unit in the foot-pound-second system; rocket propulsion engineers using US customary units express mass flow in slug/s. A standard American rocket engine consuming 75 000 lb/s of propellant corresponds to ≈75 000/32.174 ≈ 1 830 slug/s. 1 slug/s = 14.5939029372... kg/s.
