Converters
Pressure Unit Converter
Enter a value once, pick its unit, and see it converted to every other pressure unit β pascal, bar, atm, psi, torr, and more β instantly.
Converted to all pressure units
Tip: click any row to make that unit the input.
How It Works
Every unit is converted through the pascal (Pa), the SI unit of pressure, using exact defined factors (1 bar = 100,000 Pa, 1 atm = 101,325 Pa, 1 psi = 6,894.757β¦ Pa). The list updates live as you type.
Example
1 bar = 100 kPa = 0.98692 atm = 14.5038 psi = 750.06 torr
Frequently Asked Questions
How do I convert between two specific units?
Enter your value, select the unit it's in from the "From unit" dropdown, and read the result off the row for the unit you want. Clicking a row makes that unit the new input, so you can chain conversions.
How many psi are in a bar?
1 bar = 14.5038 psi, and 1 psi = 68.948 mbar. Car tire pressures around 2.2β2.5 bar correspond to 32β36 psi.
What is a torr?
1 torr = 1/760 of a standard atmosphere β 133.322 Pa, essentially one millimeter of mercury (mmHg). It's used for vacuum and blood-pressure-style measurements.
Are the conversion factors exact?
Yes. Bar, atm, and kgf/cmΒ² are exact by definition; psi derives exactly from the pound-force and the inch (1 psi = 6,894.757293β¦ Pa); torr is exactly 101,325/760 Pa. Displayed results are rounded for readability.
