Unit Converters
Density Converter
Density — density Converter converts between density units — kg/m³, g/cm³ and lb/ft³ — through a kg/m³ base. This page runs that same calculation on your numbers, in your browser: no signup, no uploads, nothing stored.
Density Converter helps you convert a density measurement between units such as kg/m³, g/cm³ and lb/ft³. Enter your value plus the source and target units and it returns the converted density in the unit you choose instantly, right in your browser with nothing uploaded.
Pounds per cubic foot use the international pound (0.45359237 kg) and foot (0.3048 m).
About this calculator
Density Converter converts between density units — kg/m³, g/cm³ and lb/ft³ — through a kg/m³ base. It matters whenever the same quantity is expressed in two systems and a wrong factor silently breaks the answer. Here is the calculation on real numbers: Convert 1 g/cm³ to kg/m³: 1 × 1000 = 1000 kg/m³ (the density of water). For your own figures, use the calculator above — same method, your inputs, computed on-device.
How to use
- Enter the density value.
- Choose the From density unit.
- Choose the To density unit.
- Press Calculate to see the converted density.

Technical notes
Density Converter converts between density units — kg/m³, g/cm³ and lb/ft³ — through a kg/m³ base.
Conversions use standard reference factors; for trade or engineering tolerances keep more decimal places than the display shows.
The tool works offline once loaded, since every computation is client-side.
FAQ
Which density units are supported?
Kilograms per cubic metre, grams per cubic centimetre, pounds per cubic foot, and grams per millilitre.
Is 1000 kg/m³ the same as 1 g/cm³?
Yes. That is roughly the density of water, and the tool confirms it.
Why does density matter when converting units?
Density links mass and volume, so it is needed when converting between a substance's weight and volume.
Does the Density Converter send my data to a server?
No. The Density Converter runs entirely in your browser, so nothing you enter is uploaded, stored, or shared.
Worked example
Convert 1 g/cm³ to kg/m³: 1 × 1000 = 1000 kg/m³ (the density of water).
