Convert Pounds per day to Metric tons per hour
Convert Pounds per day (lb/d) to Metric tons per hour (t/h) instantly and accurately.
Conversion Formula
t/h = lb/d × 1.889968208e-5
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 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.
