Enter the gross mass (kg) and the tare mass (kg) into the Net Mass Calculator. The calculator will evaluate and display the Net Mass. 

Net Mass Formula

The following formula is used to calculate the Net Mass. 

NM = GM - TM
  • Where NM is the Net Mass (kg)
  • GM is the gross mass (kg) 
  • Tm is the tare mass (kg) 

To calculate the net mass, subtract the tare mass from the gross mass.

How to Calculate Net Mass?

The following example problems outline how to calculate Net Mass.

Example Problem #1:

  1. First, determine the gross mass (kg).
    • The gross mass (kg) is given as: 1550.
  2. Next, determine the tare mass (kg).
    • The tare mass (kg) is provided as: 750.
  3. Finally, calculate the Net Mass using the equation above: 

NM = GM – TM

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

NM = 1550 – 750 = 800 (kg)


Example Problem #2: 

For this problem, the variables needed are provided below:

gross mass (kg) = 6000

tare mass (kg) = 2350

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

NM = GM – TM = ?
