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 Short hundredweights per hour
The short hundredweight per hour (cwt/h, US) equals 45.359237/3600 ≈ 0.012600 kg/s. The US short hundredweight (100 lb exactly) is used in grain elevator and feed-mill billing sheets, cotton-gin output metering, and livestock-feed blending operations. A small feed mill might process 100-500 short cwt/h of mixed grain. 1 short cwt/h ≈ 0.012600 kg/s = 100 lb/h.
