About converting Torr to Pascals

Torr (Torr) and Pascals (Pa) are both units of pressure, so converting between them is a single multiplication: multiply your Torr figure by 133.3224. Ten Torr comes to 1,333.22 Pascals, and a hundred works out at 13,332.24 Pascals.

Rule of thumb: going from Torr to Pascals multiplies, so the figure always grows — one Torr is already 133.3224 Pascals. If your answer came out smaller, you have the conversion the wrong way round.

What is a Torr?

The torr is named after Evangelista Torricelli, who invented the mercury barometer and in the process produced the first sustained vacuum anyone had made. The unit fits that legacy exactly: it is very nearly the pressure of one millimetre of mercury, and it is still the working unit of vacuum technology, where gauges read in torr and in decimal fractions of it. Its most familiar relative is not in a laboratory at all — blood pressure is quoted in millimetres of mercury, essentially the same size, so a reading of 120 over 80 is a pressure measurement in all but name.

What is a Pascal?

The pascal is the SI unit of pressure: one newton spread over one square metre. It is named after Blaise Pascal, who established that air pressure falls with altitude by having a barometer carried up a mountain. The awkward thing about the unit is its scale — a single pascal is a very small pressure indeed, so honest real-world figures come out enormous, atmospheric pressure alone being about 101,325 of them. That is why hardly anyone works in bare pascals: engineers reach for kilopascals, meteorologists for hectopascals, and industry for the bar.

To put both in perspective: a rough vacuum pump pulls down to about 0.1 torr, while sea-level air pressure is about 101,325 pascals.

Frequently asked questions

How many Pascals are in one Torr?

There are 133.3224 Pascals in one Torr.

How do I convert Torr to Pascals?

Multiply the number of Torr by 133.3224. For example, 10 Torr = 1,333.22 Pascals.

What is 100 Torr in Pascals?

100 Torr is equal to 13,332.24 Pascals.

How do I convert Pascals to Torr?

Multiply the Pascals value by 0.007501 (or divide by 133.3224).

Is this Torr to Pascals conversion exact?

The definition is exact — Torr and Pascals are both fixed against the same base by international agreement — but the decimal shown here is rounded for readability, because the true ratio does not terminate. For engineering or scientific work, carry more decimal places than this page displays.
