Pressure Converter

The Pressure Converter is a convenient online tool that helps you convert a pressure value from one unit to another. Pressure can be measured in many different units—pascals, kilopascals, bars, atmospheres, pounds per square inch (psi), millimetres of mercury (mmHg), torr and more. Manually calculating conversions between these units can be confusing because each unit is based on different standards. This tool automates the maths and ensures your conversions are correct.

### Why use a Pressure Converter?

Engineers and scientists often need to convert pressure when working with fluid dynamics, material strength or thermodynamics. Meteorologists may convert between bars and pascals when analysing weather data, and everyday users might want to change tyre pressure from psi to bar or kPa. A pressure converter eliminates manual errors and saves time, making it easier to compare measurements and interpret data.

### How to use the tool

1. Enter the pressure value you want to convert into the input box.
2. Select the unit you are converting from (Pascal, kilopascal, bar, atmosphere, psi, mmHg, torr, etc.).
3. Choose the unit you want to convert to from the second dropdown menu.
4. Press the “Convert” button to see the converted pressure value instantly.

The interface lets you quickly switch between units and perform multiple conversions without reloading the page.
