Enter the total mass (kg) and the total volume (m^3) into the Weight Per Volume Calculator. The calculator will evaluate and display the Weight Per Volume. 

Weight Per Volume Formula

The following formula is used to calculate the Weight Per Volume. 

WPV = m * 9.81 / V

  • Where WPV is the Weight Per Volume (N/m^3)
  • m is the total mass (kg) 
  • V is the total volume (m^3) 

How to Calculate Weight Per Volume?

The following example problems outline how to calculate Weight Per Volume.

Example Problem #1:

  1. First, determine the total mass (kg). 
    1. The total mass (kg) is given as: 30.
  2. Next, determine the total volume (m^3). 
    1. The total volume (m^3) is provided as: 15.
  3. Finally, calculate the Weight Per Volume using the equation above: 

WPV = m * 9.81 / V

The values given above are inserted into the equation below:

WPV = 30 * 9.81 / 15 = 19.62 (N/m^3)


Example Problem #2: 

The variables needed for this problem are provided below:

total mass (kg) = 6

total volume (m^3) = 2

Entering these values and solving gives:

WPV = 6* 9.81 / 2 = 29.43 (N/m^3)
