About Ounces per second
The ounce per second (oz/s) equals 0.028349523125 kg/s, a practical US unit for moderate liquid or solid flow measurements. A garden hose delivering 1.5 US gal/min discharges water at roughly 2.1 oz/s; a small popcorn machine pops roughly 0.5-1 oz/s of popped corn at full rate. 1 oz/s = 0.028349523125 kg/s ≈ 0.0625 lb/s.
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.
