What it is
Pressure Converter turns pascals, kilopascals, bar, atmospheres, psi, mmHg and torr into each other as you type. 32 psi (a typical tire pressure) equals about 2.21 bar, while a blood pressure of 120 mmHg equals about 0.16 bar: psi, bar and mmHg live in the same tool, useful for comparing technical specs (tires, pneumatic systems) given in psi or bar with medical data (blood pressure) traditionally given in mmHg.
- From pascals to mmHg: 7 units, from technical to medical in one tool
- 32 psi ≈ 2.21 bar, 120 mmHg ≈ 0.16 bar: tire pressure and blood pressure compared directly
- Part of the universal converter with the other 11 families, from the /unit-converter hub
How it works
Pick the starting unit
Choose from Pa, kPa, bar, atm, psi, mmHg or torr.
Type the value
Enter the number to convert: the result in the other unit appears instantly.
Check the common table
Below the result you'll find standard multiples already converted, useful for typical pressures (1 bar, 1 atm...).
Features
psi, bar and mmHg in one tool
Compare technical data in psi or bar (tires, pneumatic systems) with medical data in mmHg (blood pressure) without switching tools: a rare combination in generic converters.
atm, bar and psi compared
1 standard atmosphere = 101,325 Pa, close to but not exactly 1 bar (100,000 Pa): the difference is small but real, and made explicit in the result.
Common conversions table
Standard multiples (0.5, 1, 2, 5 bar...) already calculated below the result, for quick comparisons against technical specs.
Part of the universal converter
The same tool as the other 11 families: jump to energy, power and other conversions from the /unit-converter hub.
FAQ
About 2.21 bar (32 × 6894.757293168 ÷ 100,000).
About 750.06 mmHg (1 bar = 100,000 Pa ÷ 133.322387415).
By historical convention, tied to mercury-column sphygmomanometers: mmHg remains the medical standard, even though it can technically be converted to any other pressure unit, as this tool shows.
1 standard atmosphere (atm) equals 101,325 Pa; 1 bar equals 100,000 Pa (close but not identical); 1 psi (pound per square inch, an imperial unit) equals about 6894.76 Pa.
Carmakers typically recommend 29-36 psi (about 2.0-2.5 bar): convert your specific placard value with this tool to go from psi to bar or back.
