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 tons per hour
The short ton per hour (ton/h, US) equals 907.18474/3600 ≈ 0.25199 kg/s, the standard capacity unit for US aggregate crushers, coal-fired power plants, and pellet mills. ASHRAE steam-boiler size references, cement plant kiln output, and mine-hoist capacity are all quoted in short ton/h. A large gyratory crusher processes 1 000-3 000 short ton/h. 1 short ton/h ≈ 0.25199 kg/s ≈ 0.9072 t/h.
