Conversion Formula

mg/d = g/h × 24000

About Grams per hour

The gram per hour (g/h) equals 10⁻³/3600 ≈ 2.778×10⁻⁷ kg/s, used in fuel-cell hydrogen consumption tests, precision agricultural sprayers, and humidity calibration. A 1 kW PEM fuel cell consumes roughly 750 g/h of hydrogen at rated power. Automotive air-conditioning refrigerant leak standards are set in g/h. 1 g/h ≈ 2.778×10⁻⁷ kg/s = 1/3600 g/s.

About Milligrams per day

The milligram per day (mg/d) equals 10⁻⁶/86400 ≈ 1.157×10⁻¹¹ kg/s, used in toxicology (daily intake limits) and in slow-release pharmaceutical implants. WHO acceptable daily intake for food additives is expressed in mg/kg body mass per day; a 70 kg adult at 1 mg/kg/d represents a 70 mg/d dose. 1 mg/d ≈ 1.157×10⁻¹¹ kg/s.
