This converter turns torr into pascals instantly, using the exact factor 1 torr = 133.3223684 pascals. Type any number and the result updates as you go — nothing is sent to a server, so the arithmetic happens entirely in your browser.
One millimetre of mercury, used in vacuum work. The SI unit: one newton per square metre.
Because the relationship is a simple proportion, one multiplication does the whole job. The table further down gives pre-computed values for the amounts people look up most often, and the result panel also reports the reverse conversion so you can check the figure both ways.
The formula
torr- The amount you are converting, measured in torr
133.3223684- The exact number of pascals in one torr
pascals- The converted result
How it works, step by step
- Enter the number of torr you want to convert.
- The value is multiplied by 133.3223684, the exact conversion factor.
- The result is displayed in pascals, rounded for readability.
- The unrounded value and the reverse conversion appear underneath so you can verify it.
Worked examples
Converting 5 torr
Multiply 5 by 133.32237. That gives 666.6118 pascals. A quick sanity check: one torr is larger than one pascal, so the number should get bigger — and it does.
Converting 72 torr
72 × 133.32237 = 9,599.21 pascals. Working backwards, 9,599.21 ÷ 133.32237 returns 72 torr, which confirms the factor is applied the right way round.
How to read your score
Frequently asked questions
How many pascals are in one torr?
Exactly 133.3223684. Every conversion on this page is that single number multiplied by your input, so the result carries no rounding error beyond what is shown.
What is the formula to convert torr to pascals?
Pascals = torr × 133.3223684. To reverse it, divide instead: torr = pascals ÷ 133.3223684, which is the same as multiplying by 0.007500616827.
Is the torr bigger than the pascal?
Yes. One torr equals 133.322 pascals, so it is the larger unit.
Why does my answer differ slightly from other torr to pascals converters?
Most differences come from rounding the factor too early. This tool keeps full double precision through the calculation and only rounds at the final display step, and it also shows the unrounded value so you can see exactly where any difference appears.
