Conversion Formula

µg/s = lb/d × 5249.91169

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 Micrograms per second

The microgram per second (µg/s) equals 10⁻⁹ kg/s, the working unit for ultra-trace flow measurements. HPLC pumps delivering isotopic tracers, or nanoliter dispense systems in drug-discovery robotics, operate at µg/s throughput. A 1 µl/min water stream at 1 g/cm³ corresponds to ≈16.7 µg/s. 1 µg/s = 10⁻⁹ kg/s = 60 µg/min.
