Conversion Formula
g/s = lb/d × 0.00524991169
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 second
The gram per second (g/s) equals 10⁻³ kg/s, a practical laboratory and light-industrial unit. Water flowing from a standard kitchen tap runs at roughly 60-80 g/s; a 3D printer extruder deposits filament at 0.5-2 g/s; an automated pill-dispensing machine doses powders at 1-10 g/s. It is also the preferred unit for small engine fuel-consumption test benches. 1 g/s = 10⁻³ kg/s = 3.6 kg/h.
