Cement Calculator
Cement weight is calculated by multiplying volume by density. Typical cement density is about 1440 kg/m³, but it varies by type and source. Use this calculator to convert any volume to kilograms.
What Is Cement?
Cement weight is the mass of cement required for a given volume, calculated as volume multiplied by density. Standard Portland cement density is about 1440 kg/m³, though blended cements may differ. This calculator converts any input volume to kilograms using your chosen density.
Example
Formula: Volume x Density = 2 m³ x 1440 kg/m³ = 2880 kg
Select volume and density units, then the result will be in kg.
Tip: Choose your result unit on the right before calculating.
Step-by-step calculation
- Enter cement volume and density with units.
- Calculate to see cement weight in kg.
How this is calculated
This calculator converts cement volume to mass using the standard relation mass = volume × density. It uses 1440 kg/m³ for ordinary Portland cement by default, which matches typical bulk densities used in mix-design references. For blended or sulfate-resisting cements, enter the density printed on the bag or spec sheet. Results are estimates for planning only and should be confirmed against supplier batch data before ordering.

FAQ
- How do I calculate cement weight by hand?
- Multiply volume (m³) by density (kg/m³). Example: 2 m³ x 1440 kg/m³ = 2880 kg.
- What is the formula for cement weight?
- Weight = Volume x Density. Use 1440 kg/m³ for standard Portland cement.
- Portland cement vs blended cement
- Portland is about 1440 kg/m³; blended cements may be 1300–1500 kg/m³ depending on additives.
- What units should I use?
- Use m³ or L for volume, and kg/m³ for density. The result is in kg.
- Can I use this for mortar or plaster?
- Yes. Enter the cement volume for your mortar or plaster mix to get the weight.
