Enter the total power (watts) and the total area (m^2) into the Calculator. The calculator will evaluate the Power Per Square Meter. 

Power Per Square Meter Formula

PPSM = P / A


  • PPSM is the Power Per Square Meter (watts/m^2)
  • P is the total power (watts)
  • A is the total area (m^2)

To calculate the Power Per Square Meter, divide the total power by the total area.

How to Calculate Power Per Square Meter?

The following steps outline how to calculate the Power Per Square Meter.

  1. First, determine the total power (watts). 
  2. Next, determine the total area (m^2). 
  3. Next, gather the formula from above = PPSM = P / A.
  4. Finally, calculate the Power Per Square Meter.
  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 power (watts) = 780

total area (m^2) = 123
