Torr Converters

Convert torr to pascals, kilopascals, atmospheres, psi, bar, millibar and millimeters of mercury.

What this tool does

Convert torr to pascals, kilopascals, atmospheres, psi, bar, millibar and millimeters of mercury. Type an amount in torr, choose the units, and the tool converts it to pascals. It offers 8 pressure units and also shows the same amount in the others.

Inputs

  • Value: A number.
  • From: Choose one: Torr, Millimeter of mercury (conventional), Pascal, Kilopascal, Millibar, Bar, Standard atmosphere, Pound-force per square inch (psi). Starts as Torr.
  • To: Choose one of the same 8 units as "From". Starts as Pascal.

How to use

  1. Enter the amount you want to convert.
  2. Choose the unit to convert from and the unit to convert to.
  3. Read the result: the converted amount and the same amount in the other units. It appears once every required field has a valid value.

Worked examples

Conversions from torr to pascals:

  • 1 Torr ≈ 133.322368 Pa
  • 5 Torr ≈ 666.611842 Pa
  • 10 Torr ≈ 1,333.223684 Pa
  • 50 Torr ≈ 6,666.118421 Pa
  • 100 Torr ≈ 13,332.236842 Pa

Multiply the number of torr by about 133.322368 to get pascals. The factor follows from exact definitions. It has more digits than fit here, so it is shown rounded.

Sources: Torr: NIST SP 811 (2008), Appendix B.8. Pascal: SI Brochure, 9th edition (2019).

Limitations

  • Converts pressure units only. It does not label a vacuum level.
  • Millimeters of mercury use the conventional definition.

FAQs

Q: How many pascals are in one torr?
A: One torr is exactly 101,325/760 pascals, which is about 133.32 Pa.
Q: Is a torr the same as a millimeter of mercury?
A: Nearly. They differ by about one part in seven million, so for any practical reading they are equal. Both are listed separately.
Q: How many torr are in one atmosphere?
A: Exactly 760 torr make one standard atmosphere.
