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 Metric tons per minute
The metric tonne per minute (t/min) equals 1 000/60 ≈ 16.667 kg/s, used for large-scale mining conveyor capacity, bulk-carrier loading terminals, and industrial furnace melt rates. A Cape-size bulk carrier loads iron ore at 3 000-5 000 t/h = 50-83 t/min; a large electric arc furnace taps ≈100-200 t of steel per heat over roughly 60-90 min. 1 t/min = 1 000/60 kg/s ≈ 1.102 short ton/min.
