Cubic meters do not naturally convert into tons because the two units measure different properties: cubic meters (m^3) measure volume; tons, also known as U.S. or short tons, measure mass. The two different units can be made equivalent using density, which is a measurement of mass in relation to volume. If you know the density of a specific material, you can convert the volume that the material occupies in cubic meters into its mass in tons.

## Determine the Volume

## Determine the Density

## Multiply Volume by Density

## Divide by Mass

If you are using the K-TEK website, density measured in grams per cubic centimeter (g/cc) gives the same ratio as kilograms per cubic meter (kg/m^3) so no conversion is necessary.

Determine the volume in cubic meters of your material. For example, you have 500,000 m^{3} of rye.

Determine the density of your material with an online material density chart (see Resources). In this example, rye has a density of 705 kilograms per cubic meter.

Multiply the volume of the material by its density to obtain the material's mass. In this example, 500,000 x 705 = 352,500,000. You have 352,500,000 kg of rye.

Divide the mass in kilograms by 907.18 to convert it to tons. In the example, 352,500,000/907.18 = 388,566.77. You have 388,566.77 tons of rye.
