About Grains per minute

The grain per minute (gr/min) equals 6.479891×10⁻⁵/60 ≈ 1.080×10⁻⁶ kg/s. This unit appears in HVAC humidity engineering: moisture added or removed from conditioned air is traditionally expressed in grains of water per pound of dry air per minute in US practice. A whole-house humidifier may evaporate 300-600 gr/min at design load. 1 gr/min ≈ 1.080×10⁻⁶ kg/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.
