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 Metric tons per hour

The metric tonne per hour (t/h) equals 1 000/3600 ≈ 0.27778 kg/s, the dominant capacity unit in European and international process engineering. Equipment datasheets for conveyor belts, crushers, mills, dryers, compactors, and cyclone separators specify throughput in t/h. A 500 MW coal plant consumes ≈70-90 t/h of pulverised coal; a large rotary cement kiln produces ≈200-300 t/h of clinker. 1 t/h = 1 000/3600 kg/s ≈ 1.102 short ton/h.
