MihsabaHow to use
This converter translates mass density between common SI, laboratory and US/imperial units. Each value is normalized through kg/m³, keeping identities such as 1 g/cm³ = 1 g/mL = 1 kg/L = 1000 kg/m³ explicit.
- Enter a non-negative density value.
- Choose the source and target units.
- Calculate to see the selected result plus useful base equivalents.
- Keep the US-gallon definition in mind for lb/gal; the imperial gallon is a different volume.
How it is calculated
Example
Unit example: 1000 kg/m³ = 1 g/cm³ = 1 g/mL = 1 kg/L, and is approximately 62.428 lb/ft³ and 8.3454 lb/US gal.
Important notes
Unit conversion does not determine the density of a material. Real material density can vary with temperature, pressure, composition and moisture. Specific gravity is a dimensionless ratio to a stated reference, so it should not automatically be treated as another density unit.
Frequently asked questions
Are g/cm³ and g/mL the same?
Yes numerically, because 1 mL is exactly 1 cm³.
Why does the converter specify US gallon?
US and imperial gallons have different volumes, so naming the gallon prevents using the wrong factor.
Can density be negative here?
No. This general mass-density converter accepts ordinary non-negative density values.
Is this calculator free?
Yes. It is free to use and requires no account.
