Enter the pressure applied to a piston and the cross-sectional area of the piston into the calculator to determine the force exerted by the piston.

Piston Force Formula

The following formula is used to calculate the force exerted by a piston.

F = P * A

Variables:

  • F is the force exerted by the piston (newtons)
  • P is the pressure applied to the piston (pascals)
  • A is the cross-sectional area of the piston (square meters)

To calculate the piston force, multiply the pressure applied to the piston by the cross-sectional area of the piston.

What is Piston Force?

Piston force is the force exerted by a piston as a result of pressure applied to it. This force is a critical parameter in the design and operation of engines, pumps, and hydraulic systems. The force determines the amount of work a piston can perform and is directly proportional to the pressure and the area over which the pressure is applied.

How to Calculate Piston Force?

The following steps outline how to calculate the Piston Force.


  1. First, determine the pressure applied to the piston (P) in pascals.
  2. Next, determine the cross-sectional area of the piston (A) in square meters.
  3. Next, gather the formula from above = F = P * A.
  4. Finally, calculate the Piston Force (F) in newtons.
  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.

Pressure applied to the piston (P) = 100,000 pascals

Cross-sectional area of the piston (A) = 0.05 square meters
