Convert Milligrams per hour to Micrograms per hour
Convert Milligrams per hour (mg/h) to Micrograms per hour (µg/h) instantly and accurately.
Conversion Formula
µg/h = mg/h × 1000
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 Micrograms per hour
The microgram per hour (µg/h) equals 10⁻⁹/3600 ≈ 2.778×10⁻¹³ kg/s, used in corrosion science to quantify mass loss rates of thin films or passive oxide layers. A stainless steel specimen losing 1 µg/h represents an extremely low corrosion rate typical of passive surfaces in neutral aqueous environments. 1 µg/h = 1/3600 µg/s ≈ 2.778×10⁻¹³ kg/s.
