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 for 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.

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.
