Hydraulic Force Formulas
Extend Force (Push Force): F = P × A = P × π × (D/2)²
Retract Force (Pull Force): F = P × A = P × π × [(D/2)² – (d/2)²]
Where:
- F = Force (lbs)
- P = Pressure (PSI)
- D = Piston Diameter (inches)
- d = Rod Diameter (inches)
- π = Pi (~3.1416)
How to Use This Calculator
- Enter the hydraulic system pressure in PSI
- Enter the piston diameter in inches
- Enter the rod diameter in inches (for retract force calculation)
- Select whether you want to calculate extend force, retract force, or both
- Click “Calculate Force” to see results
Note: For extend force only, rod diameter is not required.
