Convert Micrograms per litre to Slugs per cubic foot
Convert Micrograms per litre (µg/L) to Slugs per cubic foot (slug/ft³) instantly and accurately.
Conversion Formula
slug/ft³ = µg/L × 1.940320332e-9
About Micrograms per litre
The microgram per litre (µg/L) equals 10⁻⁶ kg/m³, numerically equal to mg/m³, and the standard unit for trace-level water quality. EPA maximum contaminant level for arsenic is 10 µg/L; WHO guideline for lead in drinking water is 10 µg/L; pharmaceutical water-for-injection requires total organic carbon below 500 µg/L. 1 µg/L = 10⁻⁶ kg/m³ = 1 mg/m³ = 1 ppb (mass) in dilute aqueous solutions.
About Slugs per cubic foot
The slug per cubic foot (slug/ft³) equals ≈515.379 kg/m³, used in US customary dynamics where forces are in pound-force. The US Standard Atmosphere gives sea-level air density as 2.377 × 10⁻³ slug/ft³; it appears in pre-SI aerospace textbooks (NACA technical notes) and compressible flow equations. 1 slug ≈14.594 kg. 1 slug/ft³ ≈515.379 kg/m³ ≈32.174 lb/ft³.
