Enter the total pressure of the ram and the cross-sectional area of the ram into the calculator to determine the hydraulic ram force.

Hydraulic Ram Force Formula

The following equation is used to calculate the Hydraulic Ram Force.


  • Where HRA is the hydraulic ram force (lbf)
  • P is the pressure delivered by the hydraulics (PSI)
  • A is the cross-sectional area of the ram (in^2)

To calculate the hydraulic ram force, multiply the pressure by the area.

What is a Hydraulic Ram Force?


The ram force of a hydraulic ram is the force that is exerted on the cylinder of the ram. It is measured in pounds per square inch (PSI).

How to Calculate Hydraulic Ram Force?

Example Problem:

The following example outlines the steps and information needed to calculate the hydraulic ram force.

First, determine the pressure. For this problem, the hydraulic pressure is measured to be 500 psi.

Next, determine the cross-sectional area of the ram. This ram has a cross-sectional area of 10 square inches.

Finally, calculate the hydraulic ram force using the formula above:


HRF = 500*10

HRF = 5,000 lbf
