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 Micrograms per hour
The microgram per hour (µg/h) equals 10⁻⁹/3600 ≈ 2.778×10⁻¹³ kg/s, used in corrosion science to quantify mass loss rates of thin films or passive oxide layers. A stainless steel specimen losing 1 µg/h represents an extremely low corrosion rate typical of passive surfaces in neutral aqueous environments. 1 µg/h = 1/3600 µg/s ≈ 2.778×10⁻¹³ kg/s.
