PRESSURE FORMULAS

FIND PRESSURE
P = F ÷ A
Divide force by area.
FIND FORCE
F = P × A
Multiply pressure by area.
FIND AREA
A = F ÷ P
Pressure must not be zero.
UNITS
N and m² give Pa.
1 Pa = 1 N/m².

WORKED EXAMPLES

PRESSURE
F = 120 N, A = 0.5 m²
P = 120 ÷ 0.5 = 240
Answer: 240 Pa
FORCE
P = 80 Pa, A = 3 m²
F = 80 × 3 = 240
Answer: 240 N
AREA
F = 500 N, P = 250 Pa
A = 500 ÷ 250 = 2
Answer: 2 m²
CHECK
A smaller area gives larger pressure for the same force.

WHAT THIS TOOL DOES

This pressure calculator finds pressure, force or area from two known values.

It uses the GCSE physics formula P = F ÷ A and the rearranged versions F = P × A and A = F ÷ P.

The working panel shows the formula, substituted values and final rounded answer.

Canonical folder: /pressure-calculator/

HOW TO USE IT

Choose whether to find pressure, force or area on Page 1.

Enter the two known values in the visible input boxes.

Press SOLVE to calculate the answer and show the working.

Use EXAMPLE to restore the sample values, or CLEAR to reset the tool.

UNIT SAFETY

Use newtons for force and square metres for area when calculating pascals.

Pressure in pascals means newtons per square metre.

If area is given in cm² or mm², convert it to m² before using the calculator.

Incorrect area units are the most common pressure calculation mistake.

WHO USES IT

Students use this page for GCSE physics, combined science and mechanics homework.

Teachers and tutors can use it to show rearranging equations and checking units.

It is useful for contact force, surface area, tyres, shoes, solids and simple pressure questions.

The calculator stays on Page 1 so the working tool is always quick to reach.

COMMON SEARCHES

People may search for pressure calculator, force area pressure calculator or pressure formula calculator.

Other searches include calculate pressure from force and area, P equals F over A, and pressure formula with working.

This page supports those searches with a working calculator, formula help and readable internal pages.

GCSE HOMEWORK HELP

GCSE users may search for physics pressure calculator, pressure mass force help or force area pressure GCSE.

Homework searches may ask how to calculate pressure, how to find force from pressure, or how to find area from pressure.

The calculator answers these tasks by showing the formula, substituted values and rounded final result.

FAQ: FORMULA

What formula is used? Pressure equals force divided by area.

What unit is pressure? Pascals, written Pa, or newtons per square metre.

Can it find force? Yes. Choose FORCE and use F = P × A.

Can it find area? Yes. Choose AREA and use A = F ÷ P.

FAQ: ANSWERS

Why is my answer wrong? Check that area is in square metres.

Can pressure be zero? A zero pressure value cannot be used when finding area.

Does rounding affect working? Rounding is applied only to the final displayed answer.

Can I use decimals? Yes. Decimal force, area and pressure values are supported.

SEARCH INTENT COVERAGE

This page is designed for users who need a fast answer, a visible formula and clear working.

It covers calculation intent, revision intent, homework intent and formula rearranging intent.

The support text is split across full-size reading panels instead of compressed SEO boxes.

PRACTICAL USE CASES

Use pressure to compare how the same force acts on small and large contact areas.

Use force and area calculations when a worksheet gives two values and asks for the missing one.

For exam answers, write the formula, substitute the values, calculate, then add the correct unit.
