Convert Gram per Cubic Meter to Tonne per Cubic Meter

Input the number of grams per cubic meter you want to convert to tonnes per cubic meter.

1 g/m³ (grams per cubic meter) = 1e-6 t/m³ (tonnes per cubic meter)

How to Convert Grams per Cubic Meter to Tonnes per Cubic Meter

The gram per cubic meter and tonne per cubic meter are both units of density. By definition, 1 tonne per cubic meter equals exactly 1000000 grams per cubic meter. This means to convert grams per cubic meter to tonnes per cubic meter, you divide by 1000000.

Formula

tonnes per cubic meter = grams per cubic meter ÷ 1000000

Step-by-Step Example

Convert 5 g/m³ to tonnes per cubic meter:

1
Convert 5 g/m³ to tonnes per cubic meter

We need to convert grams per cubic meter to tonnes per cubic meter

2
Apply the formula

Since 1 t/m³ = 1000000 g/m³, divide by 1000000

5 ÷ 1000000 = 5e-6

Answer

5 g/m³ = 5e-6 t/m³

About These Units

Gram per Cubic Meter (g/m³)

Grams per cubic meter (g/m³) measures gas densities and aerosol concentrations. Air: ~1,225 g/m³. Hydrogen: ~90 g/m³. Used for air quality (PM2.5 in μg/m³), industrial emissions, and atmospheric science. Converts easily to mg/L.

Tonne per Cubic Meter (t/m³)

Tonnes per cubic meter (t/m³) equals kg/L and g/cm³. Used for bulk materials: concrete 2.4 t/m³, granite 2.7 t/m³, water 1.0 t/m³. Common in construction, mining, and aggregate industries for estimating material weights.
