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 second
The long ton per second (long ton/s) equals 1 016.0469088 kg/s, based on the UK long ton of 2 240 lb used historically in British heavy industry and naval engineering. It quantifies extremely high discharge rates such as large dam break surges or catastrophic industrial spillages. 1 long ton/s = 1 016.0469088 kg/s ≈ 1.016 t/s ≈ 1.120 short ton/s.
