About Short hundredweights per day
The short hundredweight per day (cwt/d, US) equals 45.359237/86400 ≈ 5.249×10⁻⁴ kg/s. It appears in US agricultural reports where daily throughput of commodity crops (corn, soybeans, hay) or daily milk yield per herd is stated in short cwt/d. A modern dairy farm averaging 80 lb/cow/d at 1 000 cows produces 800 cwt/d. 1 short cwt/d ≈ 5.249×10⁻⁴ kg/s.
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.
