Pressure Converter

A Versatile Tool for Pressure Units

This comprehensive Pressure Converter allows you to switch between various units of pressure, including Pascals (Pa), bars, atmospheres (atm), Torr, and pounds per square inch (psi). It's an essential tool for engineers, scientists, divers, and anyone working with fluid dynamics or pneumatics.

The Conversion Formula Explained

The calculator works by converting your input value into a base unit (Pascals) and then converting that value into your desired target unit. Example Formula: To convert psi to Pascals, the formula is: Pascals = psi * 6894.76

How to Use the Calculator

1. Enter Value: Input the pressure value you want to convert.
2. Select 'From' Unit: Choose the starting unit of pressure.
3. Select 'To' Unit: Choose the target unit of pressure. The converted result will appear instantly.

Real-World Example

Your car tire pressure is 32 psi. You want to know what this is in bars.

1. Enter 32 in the 'From' field.
2. Select Pound-force per square inch (psi) as the 'From' unit.
3. Select Bar as the 'To' unit. The calculator will show the result: 2.21 bar.

Frequently Asked Questions (FAQ)

• What are these different units used for?
  • Pascal (Pa): The SI unit of pressure, often used in scientific contexts.
  • psi: Commonly used in the US for things like tire pressure.
  • Bar: Widely used in meteorology and for tire pressure in metric countries. 1 bar is approximately equal to atmospheric pressure at sea level.
  • Atmosphere (atm): Defined as the average atmospheric pressure at sea level.
  • Torr: Often used for measuring vacuum pressures.
• What is the difference between absolute and gauge pressure? Gauge pressure is measured relative to the surrounding atmospheric pressure. Absolute pressure is measured relative to a perfect vacuum. This converter simply converts the numerical value of a pressure, regardless of whether it's gauge or absolute.
