Hydraulic Force Calculator

Information

Calculate hydraulic cylinder forces (forward and backward) from pressure and cylinder dimensions.

How to Use:

1. Set Pressure: Enter system pressure in bar, or click a standard pressure button (32-280 bar per ISO 4401)
2. Set Cylinder Size: Enter piston and rod diameters in mm, or click a standard ISO cylinder set
3. View Results: Forward force = extension force; Backward force = retraction force
4. Copy Values: Click any result value (underlined) to copy it to clipboard
5. Details: See full calculation breakdown below the results

Unit Conversions:
1 bar = 100,000 Pa
1 Pa = 1 N/m²
1 N = 0.102 kgf
1 mm = 0.001 m
