About this online calculator

This calculator uses the density formula to calculate density, mass or volume. Density is defined as mass per unit volume. Along with values, enter the known units of measure for each and this calculator will convert among units.

Significant Figures

For example, 4 significant figures for 165778 will become 165800 while 4 significant figures for 0.00165778 will become 0.001658.  See also our help notes on significant figures.

Formula for density.

p = M/V

density, p = mass/volume

Density calculations:

Solving for density, mass or volume we can use the following formulas:

  • Calculate p Given M and V
    Calculate density given mass and volume.
    • p = M/V
  • Calculate M Given p and V
    Calculate mass given density and volume.
    • M = pV
  • Calculate V Given p and M
    Calculate volume given density and mass.
    • V = p/M
  • Cube root of Volume
  • Cube root of volume, 3√ V, is shown to help in the mental visualization of the actual volume.  Thanks again to the user that suggested this calculator!
