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 /1000
  • Where WM is the Water Mass (kg)
  • VW is the total volume of water (L) 
  • DW is the density of the water (kg/m^3) 

To calculate the water mass, simply multiply the volume of water by the density of water.

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 = ?
