Conversion Formula

µg/h = gr/h × 64798.91

About Grains per hour

The grain per hour (gr/h) equals 6.479891×10⁻⁵/3600 ≈ 1.800×10⁻⁸ kg/s, used in HVAC psychrometric calculations for dehumidifier capacity and moisture-removal rates. ASHRAE load calculation spreadsheets report latent loads in grains of water per hour; a typical residential dehumidifier removes 5×10⁵-2×10⁶ gr/h. 1 gr/h ≈ 1.800×10⁻⁸ 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.
