Reference densities

Water1 g/cm³
Ice0.92 g/cm³
Aluminum2.7 g/cm³
Iron7.87 g/cm³
Copper8.96 g/cm³
Lead11.34 g/cm³
Gold19.32 g/cm³
Air0.0013 g/cm³

Result

Calculated density

2.000
g/cm³

Formula

ρ = m / V
Density = Mass / Volume
ρ (rho) = Density (g/cm³)
m = Mass (grams)
V = Volume (cm³)
Calculating: ρ = 100 g / 50 cm³ = 2.000 g/cm³

Unit Conversions

1 g/cm³ = 1000 kg/m³
1 cm³ = 1 mL
1000 cm³ = 1 L
1 kg = 1000 g

About Density Calculator

Calculate Density, Mass, or Volume

This calculator uses the fundamental density formula ρ = m/V to calculate any of the three variables when the other two are known. Density is a measure of how much mass is contained in a given volume.

Features

  • Calculate density from mass and volume
  • Calculate mass from density and volume
  • Calculate volume from mass and density
  • Common material densities reference
  • Unit conversion guide
  • Step-by-step formula display
  • High precision results
  • Easy mode switching

Understanding Density

Density is an intensive property that describes how tightly matter is packed together. Materials with higher density have more mass per unit volume. For example, gold is much denser than water, which is why it sinks.

Applications

  • Material identification and quality control
  • Chemistry and physics experiments
  • Engineering design calculations
  • Determining if objects will float or sink
  • Geology and mineralogy studies
  • Manufacturing and production

Tips

  • Ensure all measurements use consistent units
  • For irregular objects, use water displacement to find volume
  • Temperature affects density (most materials expand when heated)
  • Density of water at 4°C is exactly 1.0 g/cm³
