What this calculator does

Density relates how much mass is packed into a volume. Solve for density, mass or volume from the other two, and check whether an object would float in water.

Formula and method

ρ = m ÷ V; m = ρ × V; V = m ÷ ρ

Worked example

Calculated by this tool with its default inputs:

Inputs

  • Solve for: Density
  • Mass: 2 kg
  • Volume: 0.001 m³

Results

  • Density: 2,000 kg/m³
  • In g/cm³: 2 g/cm³
  • In fresh water (≈ 1000 kg/m³) it would: Sink

How to read the results

Objects denser than the fluid sink; less dense objects float.

Assumptions and limitations

  • Fresh water ≈ 1000 kg/m³; seawater ≈ 1025 kg/m³.

These are educational estimates. Electrical, structural and other safety-critical work must comply with local codes and be designed or checked by a qualified professional.

Questions

What is the density of water?

About 1000 kg/m³ (1 g/cm³) near 4 °C.
