Convert Milligrams per hour to Grams per hour
Convert Milligrams per hour (mg/h) to Grams per hour (g/h) instantly and accurately.
Conversion Formula
g/h = mg/h × 0.001
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.
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.
