About Short tons per minute
The short ton per minute (ton/min, US) equals 907.18474/60 ≈ 15.120 kg/s, typical for high-capacity conveyor belts and bucket-wheel excavators in open-cast mining. A large surface coal mine loads unit trains with overland conveyors rated at 5 000-15 000 short ton/h = 83-250 ton/min. 1 short ton/min ≈ 15.120 kg/s = 2 000 lb/min.
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.
