Weight Calculator

Construction Calculator

Calculate the estimated weight of construction materials from their volume and density. Choose a common material or enter your own density for concrete, sand, gravel, stone, cement, soil and other materials.

Calculate Material Weight

How it works: Weight is calculated from volume multiplied by density. Material densities are approximate and can vary with moisture, compaction, composition and product specifications.

Estimated Weight

Calculated weight 0 kg
Kilograms 0 kg
Metric tonnes 0 t
Pounds 0 lb
US tons 0 tons

How the Weight Calculator Works

The basic relationship between material weight, volume and density is simple. Weight is calculated by multiplying volume by density.

For example, if you know the volume of concrete required for a project, you can use an approximate concrete density to estimate the total material weight.

Weight Formula

Weight = Volume x Density

The calculator converts the entered volume and density into compatible units before performing the calculation. You can work with cubic meters, cubic feet, cubic yards, liters or US gallons.

Common Material Densities

The calculator includes approximate reference densities for common construction materials. Actual density can vary depending on the material source, moisture content, grading, compaction and product specifications.

Concrete Approximately 2,400 kg per cubic meter
Sand Approximately 1,600 kg per cubic meter
Gravel Approximately 1,680 kg per cubic meter
ABC Stone / Aggregate Approximately 1,800 kg per cubic meter
Limestone Approximately 1,550 kg per cubic meter
Soil Approximately 1,500 kg per cubic meter
Cement Approximately 1,440 kg per cubic meter
Water Approximately 1,000 kg per cubic meter

Example Weight Calculation

Suppose you have 2 cubic meters of concrete and use an approximate density of 2,400 kilograms per cubic meter.

Weight = 2 x 2,400 = 4,800 kilograms

That is approximately 4.8 metric tonnes. Actual material weight can differ because concrete density depends on its mix and aggregate composition.

Weight Calculator FAQs

How do I calculate the weight of a material?
Multiply the material volume by its density. The basic formula is weight equals volume multiplied by density. The calculator performs the required unit conversions automatically.
Can I calculate concrete weight with this calculator?
Yes. Select Concrete, enter the volume and choose the appropriate volume unit. The calculator uses an approximate concrete density to estimate the weight.
Can I enter my own material density?
Yes. Select Custom Material and enter the density supplied by the manufacturer, laboratory test or project specification.
Why can actual material weight differ from the estimate?
Material density can change because of moisture, compaction, aggregate size, composition, porosity and other physical characteristics. Actual material weight may therefore differ from an estimate based on a standard reference density.
What is the difference between kilograms and metric tonnes?
One metric tonne equals 1,000 kilograms. The calculator displays both units so you can use the result in the format most suitable for your project.
Can I calculate the weight of sand, gravel and stone?
Yes. The calculator includes approximate reference densities for sand, gravel, ABC stone and limestone. For a specific product, use the Custom Material option if you have its verified density.
