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 minute
The microgram per minute (µg/min) equals 10⁻⁹/60 ≈ 1.667×10⁻¹¹ kg/s, used in capillary electrophoresis and gas chromatography mass flow calibration. A typical cold-trap atmospheric sampler collecting particulate matter draws air at a rate characterized in µg/min of PM2.5. 1 µg/min = 1/60 µg/s ≈ 1.667×10⁻¹¹ kg/s.
