Enter the total volume of water (m^3) and the density of the water (kg/m^3) into the Water Mass Calculator. The calculator will evaluate and display the Water Mass. 

Water Mass Formula

The following formula is used to calculate the Water Mass. 

WM = VW * DW

  • Where WM is the Water Mass (kg)
  • VW is the total volume of water (m^3) 
  • DW is the density of the water (kg/m^3) 

How to Calculate Water Mass?

The following example problems outline how to calculate Water Mass.

Example Problem #1:

  1. First, determine the total volume of water (m^3). 
    • The total volume of water (m^3) is given as: 13.
  2. Next, determine the density of the water (kg/m^3). 
    • The density of the water (kg/m^3) is provided as: 997.
  3. Finally, calculate the Water Mass using the equation above: 

WM = VW * DW

The values given above are inserted into the equation below and the solution is calculated:

WM = 13*997 = 12,961 (kg)


Example Problem #2: 

For this problem, the variables needed are provided below:

total volume of water (m^3) = 6

density of the water (kg/m^3) = 997

This example problem is a test of your knowledge on the subject. Use the calculator above to check your answer. 

WM = VW * DW = ?
