Background
Engineering basis, equations, assumptions, interpretation and practical limitations for this calculator.
Volume = mass ÷ density
Mass = density × volume
Material density varies with composition, temperature, moisture and compaction.
Use a measured or supplier density for purchasing and transport. Bulk materials such as soil, sand and aggregate can vary substantially.

Frequently Asked Questions
Practical questions about assumptions, inputs, interpretation and limitations.
Density can change with temperature, moisture content, composition, porosity, entrained air and compaction. For powders and granular materials, loose and compacted bulk density may differ substantially.
No. Bulk density includes the void spaces between particles, while particle density describes the material making up the particles themselves. Use the density value that matches the quantity you are trying to convert.
Yes. Enter the liquid density at the relevant temperature. Liquid density can vary with temperature and composition, so use a representative value when accuracy matters.
The converter uses density = mass / volume. Rearranging gives volume = mass / density and mass = density × volume. Unit conversions are applied around the same physical relationship.
Use measured or specification density when the result matters. Typical material values are useful for estimates, but real materials can differ because of moisture, composition, voids and manufacturing tolerances.
