This example exercises the same calculator formula and unit factors as the interactive page. It demonstrates unit equivalence only and does not claim that an unknown material has any particular identity.
Substitute mass and volume
ρ = m/V = 1 kg ÷ 1 L. Because 1 L is exactly 0.001 m³, the coherent SI calculation is 1 kg ÷ 0.001 m³ = 1000 kg/m³.
Convert both parts of the unit
The same pair is 1000 g ÷ 1000 cm³ = 1 g/cm³. Since 1 cm³ equals 1 mL exactly, the result is also 1 g/mL and 1 kg/L.
Do not infer a substance
A numerical density near a reference value is not proof of composition, purity, temperature, pressure, porosity, or measurement quality. This example verifies arithmetic only.
