How this calculator works
The result depends on the numbers you enter and the assumptions shown below.

Density (ρ) = mass / volume. Water has a density of 1 g/cm³. Objects denser than water sink; less dense objects float. Common units: g/cm³ for solids/liquids, kg/m³ in SI.

Review the inputs carefully and treat the output as an estimate. For decisions involving money, taxes, health, law, or security, compare the result with trusted professional guidance when needed.

Frequently asked questions

What is the density of water?

Water is 1 g/cm³ (1000 kg/m³) at 4°C. Most other common liquids are close to this value. Gold is 19.3 g/cm³; aluminum is 2.7 g/cm³.
