Where this conversion is used
Torr is still the most common unit on vacuum gauges, deposition tools and in American vacuum literature, while the pascal is the SI unit used in standards and calculations. Multiplying by 133.322 converts Torr to Pa.
1 Torr is defined as 1/760 of a standard atmosphere. It differs from the millimetre of mercury (mmHg, 133.322387 Pa) by less than 0.000015 %, so the two are interchangeable in practice.
Frequently asked questions
How many pascals are in 1 Torr?
1 Torr = 133.322 Pa. In the other direction, 1 Pa = 0.00750062 Torr.
How do I convert Torr to pascals?
Multiply the value in Torr by 133.322. Example: 0.5 Torr = 66.661 Pa.
Is Torr the same as mmHg?
Practically yes. 1 Torr = 133.322368 Pa and 1 mmHg = 133.322387 Pa, a difference of less than 0.000015 %. Torr is defined from the standard atmosphere, mmHg from a column of mercury.
How many pascals is 1 mTorr?
1 mTorr (one micron) is 0.1333 Pa, so 7.5 mTorr is about 1 Pa.
