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 Milligrams per hour

The milligram per hour (mg/h) equals 10⁻⁶/3600 ≈ 2.778×10⁻¹⁰ kg/s, adopted in transdermal drug-patch pharmacokinetics to express dermal absorption rate. A nicotine patch typically releases 14-21 mg over 24 h, corresponding to ≈0.58-0.88 mg/h. Environmental emission tests for laboratory fume hoods also express contaminant escape in mg/h. 1 mg/h = 1/3600 mg/s.
