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 Ounces per hour
The ounce per hour (oz/h) equals 0.028349523125/3600 ≈ 7.875×10⁻⁶ kg/s, seen in refrigerant-charge leak-rate specifications and slow-drip irrigation design. US EPA Section 608 refrigerant regulations set leak-rate thresholds partly in oz/year; appliance industry test methods use oz/h equivalents for comparison. 1 oz/h ≈ 7.875×10⁻⁶ kg/s.
