User Guide

This tool will calculate the pneumatic/hydraulic pressure generated by a piston cylinder for a specified force and piston-cylinder bore diameter.

Formula

The formula used by this calculator to determine the piston cylinder pressure from force and diameter is:

r = ø / 2

A = π · r² = π · (ø / 2)²

A = π · ø² / 4

P = F / A

P = 4 · F / (π · ø²)

Symbols

P = Pressure
F = Force
π = Pi = 3.14159…
r = Circle radius
ø = Circle diameter
A = Circle area

Applied Piston Force

Enter the reading in any units for the applied piston force.

Piston / Cylinder Bore Diameter

Enter the diameter of the cylinder bore or the piston, and for better precision use the average of the two if possible.

Generated Cylinder Pressure

This is the pressure generated within the cylinder with the specified diameter and applied piston force, and can be displayed in a choice of different pressure measurement units.

Questions & Answers

150 tonne & 280mm dia press

I have an application to read force in tonne (1000kg) on a 150 tonne hydraulic press with a press ram piston diameter of 280mm, and want to know what range of pressure gauge I will need to use to monitor the hydraulic pressure?

Using the above calculator a hydraulic press with a ram piston diameter of 280mm (area of 61575.2 mm²) would require a pressure of 238.894 bar to produce a force of 150 metric tonnes.
