Enter the initial water level, final water level, and mass of the object into the calculator to determine the density of the object.

Water Displacement Formula

The following formula is used to calculate density from water displacement.

D = m / (FW – IW)

  • Where D is the density g/cm^3
  • m is the mass in grams
  • FW is the final water level (mL)
  • IW is the initial water level (mL)

Water Displacement Definition

Water displacement is defined as the density of an object calculated through the displacement of a certain amount of water.


What is the water displacement method?

The water displacement method is a method for calculating the density and volume of an object. It does this through measure the amount of displaced water when the object is submerged under water that is in a container. The amount of displaced water is equal to the volume. This volume can then be used to calculate the density.
