Enter the total mass (kg) and the total area (m^2) into the Calculator. The calculator will evaluate the Mass Per Unit Area. 

Mass Per Unit Area Formula

MPA = m / A


  • MPA is the Mass Per Unit Area (kg/m^2)
  • m is the total mass (kg)
  • A is the total area (m^2)

To calculate Mass Per Unit Area, divide the total mass by the area.

How to Calculate Mass Per Unit Area?

The following steps outline how to calculate the Mass Per Unit Area.

  1. First, determine the total mass (kg). 
  2. Next, determine the total area (m^2). 
  3. Next, gather the formula from above = MPA = m / A.
  4. Finally, calculate the Mass Per Unit Area.
  5. After inserting the variables and calculating the result, check your answer with the calculator above.

Example Problem : 

Use the following variables as an example problem to test your knowledge.

total mass (kg) = 4202

total area (m^2) = 123
