Specific gravity—
Specific gravity is dimensionless: material density divided by the selected water density. The water reference is 1,000 kg/m³ at 4°C or 998.234 kg/m³ at 20°C.

Density comparison
Reference materials are illustrative, not a measurement of your sample. Air depends on pressure and temperature; liquid density changes with temperature. The chart uses a logarithmic scale.
How it works
Density is mass divided by volume (ρ = m/V). Unit conversion first expresses the input in kg/m³, then divides by the target unit factor. Round only at display time.
