About Grams per day
The gram per day (g/d) equals 10⁻³/86400 ≈ 1.157×10⁻⁸ kg/s, applied in nutritional biochemistry, pharmacology, and low-rate environmental monitoring. Human daily protein synthesis rates are in the range of 250-300 g/d; WHO recommended dietary iron intake is 8-18 mg/d; refrigerant leakage regulations cap systems at a few g/d. 1 g/d ≈ 1.157×10⁻⁸ 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.
