Convert Grams per cubic metre to Micrograms per cubic metre
Convert Grams per cubic metre (g/m³) to Micrograms per cubic metre (µg/m³) instantly and accurately.
Conversion Formula
µg/m³ = g/m³ × 1000000
About Grams per cubic metre
The gram per cubic metre (g/m³) equals 10⁻³ kg/m³, used for atmospheric moisture content and trace-gas emissions. Absolute humidity at 20°C is 8-15 g/m³ depending on relative humidity; ISO 13443 limits pipeline natural gas moisture to 65 mg/m³ (0.065 g/m³). Numerically equal to mg/L, simplifying conversion between air and water standards. 1 g/m³ = 10⁻³ kg/m³ = 1 mg/L.
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.
