## User Guide

This tool will calculate the force generated by a pressure acting over a specified surface area and display a dynamic conversion scale for each set of chosen parameters.

For example you could use this calculator to determine to force generated by a hydraulic ram, or you could determine the necessary weight to generate a calibration pressure on a deadweight tester.

### Applied Pressure

Enter the reading in any units of the applied pressure.

### Effective Area

Enter the effective surface area which the applied pressure is acting on.

### Generated Force

This is the resulting force generated by a pressure acting on a specified size of surface area and can be displayed in a choice of different force measurement units.

## Help

Do you have a question about converting pressure & area to force?

### Hydraulic bar pressure to kg force conversion

*I would like to know what the conversion figure is for converting hydraulic pressure from bar to kgf?*

If you want to calculate the force you will need to multiply the kgf/cm2 value (which is a pressure) by the cross sectional area of the hydraulic ram/cylinder in square centimeters.

If the force is 1 kgf and the area 1 cm2, then the pressure in bar would equal 1.0197162 bar.

F_{(kgf)}= P_{(bar)}x A_{(cm²)}x 1.0197162

### Converting kg/cm2 pressure to kg force

*1kg/cm² pressure = 2kg force, what is the calculation behind this?*

The relationship between pressure and force is as follows:

Pressure = Force / Area

Strictly speaking a kg/cm² is actually kgf/cm². So for a pressure of 1kgf/cm² to produce a 2kg force the surface area would be calculated as follows:

Area = Force / Pressure = 2 kgf / 1 kgf/cm² = 2 cm²

e.g. If you had a hydraulic ram with a cross sectional piston area of 2cm², a hydraulic pressure of 1 kgf/cm² would produce a force of 2 kgf.
