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 second
The short ton per second (ton/s, US) equals 907.18474 kg/s, used for the very highest industrial and military throughput rates. The Space Shuttle Main Engine consumed propellant at ≈480 kg/s LOX + 160 kg/s LH2 ≈ 640 kg/s ≈ 0.71 ton/s; a large blast-furnace tap discharges molten iron at 1-3 ton/s. 1 short ton/s = 907.18474 kg/s = 2 000 lb/s.
