About Ounces per day
The ounce per day (oz/d) equals 0.028349523125/86400 ≈ 3.281×10⁻⁷ kg/s, used in US clinical nutrition (tube-feeding rates, oral-supplement intake) and very-low flow industrial metering. A patient receiving 6 oz of enteral formula per hour (via a drip-tube) receives ≈144 oz/d. 1 oz/d ≈ 3.281×10⁻⁷ kg/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.
