Convert Pascals to Torr
1 pascal is 0.007501 Torr. One pascal is exactly 0.00750061682704 torr.
One pascal is 0.0075006168 torr. To convert pascals to torr, multiply by 0.0075006168; to go the other way, divide by 0.0075006168 or multiply by 133.32237. The factor is exact rather than rounded: it follows from NIST Special Publication 811. The SI unit: one newton spread over one square metre.

Factors are entered by hand from NIST Special Publication 811 rather than derived from a units library, so the ones that terminate are exact rather than rounded.
How do you convert pascals to torr?
- 1.Take the measurement in pascals.
- 2.Multiply by 0.0075006168 — that is how many torr fit in one pascal.
- 3.To go back the other way, divide by 0.0075006168, or multiply by 133.32237.
Worked example: 25 pascals to torr
- Formula
- Pa × 0.0075006168 = Torr
- Arithmetic
- 25 × 0.0075006168 = 0.187515 Torr
- Answer
- 25 Pa = 0.187515 Torr
The factor is rounded for display; the figure above is computed from the full value.

What is a pascal?
The SI unit: one newton spread over one square metre. It is a small pressure — a sheet of paper resting on a table is about one pascal — which is why the kilopascal is what instruments actually read.
What is a torr?
Exactly one seven-hundred-and-sixtieth of a standard atmosphere. Within a millionth of a millimetre of mercury, which is what it replaced, and still the unit of vacuum work.
How many torr are in a pascal?
One pascal is 0.0075006168 torr. Going the other way, one torr is 133.32237 pascals. Both figures come from the same defined relation rather than from a measurement, which is why they are the same today as they were in 1959.
