In physics and engineering, force, pressure, and area are closely connected. These three values help us understand how loads, weight, and fluid pressure act on surfaces. You see this relationship in everyday life, such as when sharp objects cut better than blunt ones, or when wide tires reduce ground pressure.
Instead of solving long equations by hand, a Force Pressure Area Calculator helps you quickly find the missing value when the other two are known. It works for basic physics problems and for real-world applications like hydraulics, mechanics, and engineering design.
Force Pressure Area Calculator
Physics & hydraulic cylinder force calculation using F = P × A.
Square inches (in²)
What the Force Pressure Area Calculator Is
A Force Pressure Area Calculator is an online tool based on a simple physics formula:
P = \frac{F}{A}This formula shows that pressure (P) equals force (F) divided by area (A).
The calculator allows you to:
Find pressure when force and area are known
Find force when pressure and area are known
Find area when force and pressure are known
Many versions of the calculator also include a hydraulic cylinder mode to estimate push and pull forces in hydraulic systems.
How the Force Pressure Area Calculator Works
Inputs You Enter
In normal physics mode, you enter any two of the following:
Force (F)
Pressure (P)
Area (A)
In hydraulic mode, you may enter:
System pressure
Cylinder bore diameter
Rod diameter
You can choose units like Newtons, Pascals, psi, square meters, or square inches.
Calculation Process
The calculator follows these steps:
Reads the two known values
Applies the correct formula
Converts units if needed
Displays the missing value
Output You Get
You receive:
Force in N or lbf
Pressure in Pa, psi, or bar
Area in m², in², or ft²
Hydraulic mode also shows push and pull forces.
Key Formulas Used
Pressure Formula
P = \frac{F}{A}Pressure tells how much force is applied to each unit of area.
Force Formula
F = P \times AForce increases when either pressure or area increases.
Area Formula
A = \frac{F}{P}This finds how much surface is carrying the load.
Hydraulic Cylinder Force
F = P \times A_{bore} F_{retract} = P \times (A_{bore} - A_{rod})These formulas calculate push and pull forces in hydraulic systems.
Step-by-Step Examples
Example 1: Find Pressure
Force = 800 N
Area = 200 m²
The pressure is 4 Pascals.
Example 2: Find Force
Pressure = 35 Pa
Area = 4 m²
The force is 140 Newtons.
Example 3: Find Area
Force = 950 N
Pressure = 53 Pa
The area is 17.92 square meters.
Example 4: Hydraulic Cylinder
Pressure = 2,000 psi
Bore area = 5 in²
The cylinder can push with 10,000 pounds of force.
