Conversion Formula
µg/h = lb/h × 453592370
About Pounds per hour
The pound per hour (lb/h) equals 0.45359237/3600 ≈ 1.260×10⁻⁴ kg/s, the dominant unit in US process engineering and steam-boiler rating. Packaged steam boilers are rated in lb/h of steam output (typical range 100-2 000 lb/h); HVAC cooling-coil latent loads are calculated in lb/h of moisture; flue-gas emission inventories are reported in lb/h per stack. 1 lb/h ≈ 1.260×10⁻⁴ kg/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.
