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 Pounds per day
The pound per day (lb/d) equals 0.45359237/86400 ≈ 5.249×10⁻⁶ kg/s, used in wastewater engineering for reporting biochemical oxygen demand (BOD) loads, nutrient loadings, and sludge production. US NPDES permits set effluent mass-load limits in lb/d; a municipal WWTP serving 10 000 people generates roughly 1 500-3 000 lb/d of dry sludge solids. 1 lb/d ≈ 5.249×10⁻⁶ kg/s.
