What is Density Converter?
A Density Converter is a free online unit converter that converts values between kilograms per cubic meter (kg/m3), grams per cubic centimeter (g/cm3), pounds per cubic foot (lb/ft3), pounds per US gallon (lb/gal), slugs per cubic foot (slug/ft3), and specific gravity. It computes the result locally in the browser, shows live output while you type, and also displays a full all-unit reference table so you can see the equivalent value in every density unit at once.
Key Benefits
- Convert between all common density units instantly
- See live results with high-precision formatting
- View an all-unit reference table from a single value
- Copy any result with one click
- Run fully offline with no data uploads
Common Use Cases
- •Compare material densities for engineering and materials science
- •Convert fuel or fluid densities between metric and imperial units
- •Calculate specific gravity for laboratory and quality-control work
- •Translate textbook or datasheet values across unit systems
- •Support chemistry, physics, and geology coursework
How to Convert Density Units
- Enter a value: Type the numeric density value you want to convert in the Value field.
- Choose the source unit: Select the current unit of your value, such as kg/m3, from the From unit dropdown.
- Choose the target unit: Select the unit you want the result in, such as g/cm3, from the To unit dropdown.
- Read and copy the result: The converted value updates instantly, along with a full all-unit table. Click Copy to reuse it.
Key Features
