## 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 · r^{2} = π · (ø / 2)^{2}

A = π · ø^{2} / 4

P = F / A

P = 4 · F / (π · ø^{2})

#### 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.
