How the liquid mass & volume calculator works

Mass equals volume multiplied by density. With volume in liters and density in kg/L, the result is kilograms. If mass is the starting measurement, volume in liters equals mass in kilograms divided by density. Density must be greater than zero.

One cubic meter is 1,000 liters, one metric tonne is 1,000 kilograms, and one international pound is 0.45359237 kilograms. Kilograms and pounds here are units of mass rather than force. The density unit kg/L is numerically equal to g/mL.

Density depends on the actual material, temperature and composition. The example is a fictional density rather than a product recommendation. The tool does not apply thermal expansion, pressure corrections, mixture volume changes, buoyancy or a vessel load limit.

Worked example

At an entered density of 0.85 kg/L, 1,000 L corresponds to 850 kg, 1 m³, 0.85 metric tonnes and approximately 1,873.929 pounds. Selecting mass and entering 850 kg at the same density returns 1,000 L.
