The formula
ρ = m ÷ V
Density changes with temperature, and strongly with pressure in gases. Specific gravity here compares against 1,000 kg/m³.
What to watch out for
For an irregular object, measure the volume by the water it displaces.
Frequently Asked Questions
What is the density of 5 kg in 2 L?
2,500 kg/m³, or 2.5 kg/L.
Will it float in water?
It floats if its density is below the water’s, about 1,000 kg/m³ for fresh water.
