Convert Long tons per hour to Grains per second
Convert Long tons per hour (long ton/h) to Grains per second (gr/s) instantly and accurately.
Conversion Formula
gr/s = long ton/h × 4355.555556
About Long tons per hour
The long ton per hour (long ton/h) equals 1 016.0469088/3600 ≈ 0.28224 kg/s, the traditional British equivalent of t/h still seen in pre-metric UK engineering datasheets and Lloyd's Register vessel capacity tables. An older British colliery might report winding-tower output in long ton/h; historic cement-kiln logs used long ton/h. 1 long ton/h ≈ 0.28224 kg/s ≈ 1.016 t/h.
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.
