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 Milligrams per day
The milligram per day (mg/d) equals 10⁻⁶/86400 ≈ 1.157×10⁻¹¹ kg/s, used in toxicology (daily intake limits) and in slow-release pharmaceutical implants. WHO acceptable daily intake for food additives is expressed in mg/kg body mass per day; a 70 kg adult at 1 mg/kg/d represents a 70 mg/d dose. 1 mg/d ≈ 1.157×10⁻¹¹ kg/s.
