How to use this calculator

  1. Enter the known values in the units shown. Results update as you type.
  2. Edit a calculated value to solve backwards, or lock a value to hold it fixed.
  3. Use the worked example to check the method. Reset restores the starting fields.

Formula and method

A concrete volume of 3 m³ at the Portland preset density of 2,300 kg/m³ has a mass of 6,900 kilograms.

Mass = volume × density

Worked example

Enter these known values and leave the other values blank.

Assumptions and limitations

  • No. Mix composition, entrained air and moisture affect density. This calculator uses fixed material-density presets rather than a measured mix density. The mass estimate does not determine strength, reinforcement, structural capacity or mix proportions.
  • Enter dimensions, densities and prices that describe the actual project. Quantities absent from the formula are not added automatically.

Common questions

Does the concrete-type preset replace a measured density?

No. Mix composition, entrained air and moisture affect density. This calculator uses fixed material-density presets rather than a measured mix density. The mass estimate does not determine strength, reinforcement, structural capacity or mix proportions.
