Material volume to weight calculator

Enter the volume in cubic metres and a documented density in kilograms per cubic metre for the same material condition. No material density is supplied by this tool.

How the calculation works

Mass (kg) = volume (m³) × density (kg/m³). Mass (tonnes) = kilograms ÷ 1,000.

Use the result with care

Use a density that matches the material’s condition, including moisture and packing where relevant. A density for one condition does not establish the density of another. This multiplication does not calculate compaction, specify a material mix, assess a structure or approve lifting, transport, storage or vehicle loading. Verify the actual material and the requirements of the planned handling separately.
