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 Milligrams per second

The milligram per second (mg/s) equals 10⁻⁶ kg/s, common in pharmaceutical tablet coating lines and laboratory syringe pump calibrations. A modern inkjet printhead deposits ink at roughly 1-10 mg/s per nozzle row during high-speed printing; medical infusion pumps are calibrated to this scale for drug-delivery accuracy. 1 mg/s = 10⁻⁶ kg/s = 60 mg/min.
