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.
About Long hundredweights per hour
The long hundredweight per hour (cwt/h, UK) equals 50.80234544/3600 ≈ 0.014112 kg/s. The long hundredweight (112 lb = 8 stone) was the standard commercial weight in British wholesale trade. It survives in historic UK cement and bulk-aggregate pricing sheets and in some British agricultural markets. 1 long cwt/h ≈ 0.014112 kg/s = 112 lb/h.
