Density to Mass Calculator

Mass from Density and Volume

Mass equals density times volume. When you know how dense a material is and how much space it occupies, you can find its mass without weighing it directly.

Formula

$$m = \rho \times V$$

$m$ is mass in kilograms, $\rho$ is density in kg/m³, and $V$ is volume in m³. This calculator converts common volume units to m³ automatically.

Example: water at 1000 kg/m³ filling 1 m³ has mass $m = 1000$ kg.

Applications

This relationship is used in shipping (cargo mass from tank volume), chemistry (reagent mass from solution density), and construction (material weight from slab dimensions and density).

Frequently Asked Questions

What volume units are supported?

m³, liters (L), cm³, ft³, and in³. The calculator converts your chosen unit to m³ before applying m = ρV.

Why must density be in kg/m³?

SI base units for this formula use kg/m³ for density and m³ for volume, giving mass in kilograms. Convert other density units before entering.

Can I calculate volume from mass instead?

Rearrange to V = m/ρ. This calculator finds mass from density and volume only.

Does temperature affect the result?

Density often changes with temperature. Use the density value that matches the temperature of your material.

What is the density of water?

Pure water at 4°C is approximately 1000 kg/m³ (1 g/cm³). This is a common reference for liquids and mixtures.
