Convert Pounds per day to Grams per hour
Convert Pounds per day (lb/d) to Grams per hour (g/h) instantly and accurately.
Conversion Formula
g/h = lb/d × 18.89968208
About Pounds per day
The pound per day (lb/d) equals 0.45359237/86400 ≈ 5.249×10⁻⁶ kg/s, used in wastewater engineering for reporting biochemical oxygen demand (BOD) loads, nutrient loadings, and sludge production. US NPDES permits set effluent mass-load limits in lb/d; a municipal WWTP serving 10 000 people generates roughly 1 500-3 000 lb/d of dry sludge solids. 1 lb/d ≈ 5.249×10⁻⁶ 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.
