Hydraulic Pressure Calculator

Your details

Choose which quantity you want the calculator to find. All other fields become inputs.
The force applied to the smaller (input) piston.
N
The cross-sectional area of the input (smaller) piston.
cm²
The force produced at the larger (output) piston.
N
The cross-sectional area of the output (larger) piston.
cm²
How far you push the input piston. Leave at 0 to skip distance and work calculations.

Mechanical advantage is 5.00x at 100.000 kPa system pressure.

  • This system has a mechanical advantage of 5.00: the output piston produces 5.00 times the force applied at the input.
  • An input force of 100.0 N generates 500.0 N at the output piston.
  • The hydraulic fluid transmits a pressure of 100.000 kPa equally throughout the system.

Next stepRemember: hydraulic systems trade distance for force. A higher mechanical advantage means the output piston moves a proportionally shorter distance. Account for losses due to seal friction and fluid compressibility in real systems (typically 80-95% efficiency).
