Convert Micrograms per litre to Micrograms per cubic metre
Convert Micrograms per litre (µg/L) to Micrograms per cubic metre (µg/m³) instantly and accurately.
Conversion Formula
µg/m³ = µg/L × 1000
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 Micrograms per cubic metre
The microgram per cubic metre (µg/m³) equals 10⁻⁹ kg/m³, the standard unit for ambient air quality reporting. WHO 2021 guidelines set annual mean limits for PM2.5 at 5 µg/m³ and PM10 at 15 µg/m³; NIOSH REL for nuisance dust is 10 000 µg/m³. Urban background air typically contains 10-50 µg/m³ of total suspended particles. 1 µg/m³ = 10⁻⁹ kg/m³ = 10⁻⁶ g/m³.
