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.
