Density Calculator

Calculate density (d=m/v), mass, or volume with unit conversions

Calculate Density (d = m / v)
Calculate Mass (m = d × v)
Calculate Volume (v = m / d)
Common Substance Densities (at 20°C unless noted)

About Density
Density Formula
d = m / v
where:
• d = density
• m = mass
• v = volume
Rearranged Formulas
  • Mass: m = d × v
  • Volume: v = m / d
Common Units
  • g/mL = g/cm³ (same value)
  • kg/L = g/mL (same value)
  • kg/m³ = g/L
  • Water: 1 g/mL = 1000 kg/m³
