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 Long tons per day
The long ton per day (long ton/d) equals 1 016.0469088/86400 ≈ 0.011760 kg/s, used in legacy British mining reports for daily colliery output and in Naval fuel-consumption logs. Historic British Admiralty fuel expenditure tables for Royal Navy warships used long ton/d for bunker coal or oil consumption at various speeds. 1 long ton/d ≈ 0.011760 kg/s ≈ 1.016 t/d.
