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 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.
