This converter turns pascals into torr instantly, using the exact factor 1 pascal = 0.007500616827 torr. Type any number and the result updates as you go — nothing is sent to a server, so the arithmetic happens entirely in your browser.
The SI unit: one newton per square metre. One millimetre of mercury, used in vacuum work.
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
pascals- The amount you are converting, measured in pascals
0.007500616827- The exact number of torr in one pascal
torr- The converted result
How it works, step by step
- Enter the number of pascals you want to convert.
- The value is multiplied by 0.007500616827, the exact conversion factor.
- The result is displayed in torr, rounded for readability.
- The unrounded value and the reverse conversion appear underneath so you can verify it.
Worked examples
Converting 5 pascals
Multiply 5 by 0.0075006168. That gives 0.037503 torr. A quick sanity check: one pascal is smaller than one torr, so the number should get smaller — and it does.
Converting 72 pascals
72 × 0.0075006168 = 0.540044 torr. Working backwards, 0.540044 ÷ 0.0075006168 returns 72 pascals, which confirms the factor is applied the right way round.
How to read your score
Frequently asked questions
How many torr are in one pascal?
Exactly 0.007500616827. 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 pascals to torr?
Torr = pascals × 0.007500616827. To reverse it, divide instead: pascals = torr ÷ 0.007500616827, which is the same as multiplying by 133.3223684.
Is the pascal bigger than the torr?
No. One pascal is only 0.00750062 of a torr, so the torr is the larger unit.
Why does my answer differ slightly from other pascals to torr 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.
What is a pascal?
