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 day
The short ton per day (ton/d, US) equals 907.18474/86400 ≈ 0.010499 kg/s, the capacity unit for mid-size mining operations, smelters, and US water-treatment chemical dosing. A small gold mine may process 500-1 000 short ton/d of ore; activated-sludge wastewater plants dose chemicals in short ton/d. 1 short ton/d ≈ 0.010499 kg/s ≈ 2 000 lb/d.
