About Metric tons per day
The metric tonne per day (t/d) equals 1 000/86400 ≈ 0.011574 kg/s, standard in hydrometallurgy, wastewater treatment, and environmental mass-balance reporting. A large copper smelter processes 2 000-3 000 t/d of ore; a modern desalination plant produces 100 000-500 000 t/d of potable water; IPCS industrial emission guidelines use t/d for stack mass rates. 1 t/d ≈ 0.011574 kg/s ≈ 1.102 short ton/d.
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.
