Pressure conversion is the process of changing a pressure measurement from one unit to another. Pressure is defined as the amount of force applied on a surface per unit area. Common pressure units include:

• Pascal (Pa) – SI unit of pressure
• Atmosphere (atm)
• Bar & millibar (mbar)
• Torr
• Pounds per square inch (psi)

For example, 1 atm = 101,325 Pa = 760 Torr = 14.7 psi. Instead of remembering all these conversions, our calculator makes it effortless.

Our pressure converter is designed to be quick and user-friendly. Just follow these steps:

• Step 1: Enter the pressure value into the input box.
• Step 2: Select the unit you want to convert from (e.g., atm, Pa, bar).
• Step 3: Choose the unit you want to convert to (e.g., psi, Torr).
• Step 4: Click the “Convert” button.
• Step 5: Instantly see the converted value displayed on your screen.

Whether you need one-time conversion or frequent use, the process is simple and reliable.

Here are some frequently used units of pressure and their relationships:

• 1 atm = 101,325 Pa = 1.01325 bar = 760 Torr = 14.7 psi
• 1 bar = 100,000 Pa = 0.9869 atm
• 1 psi = 6,894.76 Pa = 0.068 atm
• 1 Torr = 133.322 Pa

These conversions are already built into the calculator, so you never have to calculate manually.
