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 Grains per second
The grain per second (gr/s) equals 64.79891 mg/s or 6.479891×10⁻⁵ kg/s. The grain (= 1/7000 lb exactly) is the smallest avoirdupois mass unit, still used in ballistics for bullet and propellant-charge weights. A .308 Winchester rifle bullet of 168 gr fired in 1 s represents 168 gr/s; powder charge is typically 40-46 gr. 1 gr/s = 6.479891×10⁻⁵ kg/s = 64.79891 mg/s.
