Working

  1. 1ρ = 2700 ÷ 1000 = 2.7 g/cm³

Quick answer

Density equals mass divided by volume; water is 1 g/cm³ or 1,000 kg/m³.

The formula

ρ = m ÷ V

Frequently asked questions

What is the density of aluminium?

2.70 g/cm³ — about a third of steel, which is why it dominates aerospace and drinks cans.

Is specific gravity the same as density?

It is density relative to water, so numerically identical in g/cm³ but dimensionless.
