This converter turns torr into megapascals instantly, using the exact factor 1 torr = 0.0001333223684 megapascals. 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. Used for material strength and hydraulic systems.
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
0.0001333223684- The exact number of megapascals in one torr
megapascals- The converted result
How it works, step by step
- Enter the number of torr you want to convert.
- The value is multiplied by 0.0001333223684, the exact conversion factor.
- The result is displayed in megapascals, 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 0.00013332237. That gives 0.000667 megapascals. A quick sanity check: one torr is smaller than one megapascal, so the number should get smaller — and it does.
Converting 72 torr
72 × 0.00013332237 = 0.009599 megapascals. Working backwards, 0.009599 ÷ 0.00013332237 returns 72 torr, which confirms the factor is applied the right way round.
How to read your score
Frequently asked questions
How many megapascals are in one torr?
Exactly 0.0001333223684. 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 megapascals?
Megapascals = torr × 0.0001333223684. To reverse it, divide instead: torr = megapascals ÷ 0.0001333223684, which is the same as multiplying by 7500.616827.
Is the torr bigger than the megapascal?
No. One torr is only 0.000133322 of a megapascal, so the megapascal is the larger unit.
Why does my answer differ slightly from other torr to megapascals 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 torr?
