This page converts millitorr into kilogram-force per square centimeter using the factor 1.359509806e-06, and shows the reverse figure alongside it. Both units measure pressure, which is why one number does the whole job.
One thousandth of a torr, the working unit of vacuum deposition. Legacy metric engineering unit, still common in Asia.
Gauge versus absolute. A tyre gauge reading 32 psi means 32 psi above atmospheric, which is about 46.7 psi absolute. Converting the number is straightforward; remembering which zero it was measured from is where the mistakes happen. N/mm² and MPa are the same size, so a drawing quoting either is quoting the same stress. Two tables follow: rounded steps for quick lookup, and a set of real reference quantities converted into kilogram-force per square centimeter, which is usually more useful than the bare number.

Worked examples
A bicycle tyre: 4.65e+06 mTorr in kilogram-force per square centimeter
Take a bicycle tyre, roughly 4.65e+06 mTorr. The conversion is a single multiplication — 4.65e+06 × 1.35951e-06 — giving 6.32172 kgf/cm². Because the relationship is proportional, doubling the input doubles the answer to 12.6434 kgf/cm².
A car tyre: 1.65e+06 mTorr in kilogram-force per square centimeter
At 1.65e+06 mTorr (a car tyre), the same quantity in kilogram-force per square centimeter is 1.65e+06 × 1.35951e-06 = 2.24319 kgf/cm². One millitorr is 1.35951e-06 kilogram-force per square centimeter, so the numbers shrink as expected.
How to read your score
Frequently asked questions
How many kilogram-force per square centimeter are in one millitorr?
Exactly 1.35950980632e-06. Every figure on this page is that one number multiplied by your input, so the only rounding is at the display step.
What is the formula to convert millitorr to kilogram-force per square centimeter?
kilogram-force per square centimeter = millitorr × 1.35950980632e-06. Reversed, millitorr = kilogram-force per square centimeter ÷ 1.35950980632e-06, which is the same as multiplying by 735,559.240069.
Which is the bigger unit, the millitorr or the kilogram-force per square centimeter?
The kilogram-force per square centimeter. One millitorr is only 1.35951e-06 of a kilogram-force per square centimeter, so it takes 735,559 millitorr to make one kilogram-force per square centimeter.
What does this quantity actually measure?
Both units measure pressure. That is why a single factor is enough: there is no temperature offset and no material property involved, unlike conversions that cross between different quantities.
What is a millitorr?
One thousandth of a torr, the working unit of vacuum deposition.
What is a kilogram-force per square centimeter?
Legacy metric engineering unit, still common in Asia.
Why does my answer differ from another converter?
Almost always because the other tool rounded the factor before multiplying. This page keeps full double precision through the calculation and rounds only for display, and it prints the factor it used so you can see where any difference came from.
Is there a quick way to do mTorr to kgf/cm² in my head?
Plenty of people do this in their head: divide by 740,000 instead of using the exact factor 0.000001. At 100 that shortcut gives 0.00013513514 kilogram-force per square centimeter, off by 0.000001 kilogram-force per square centimeter or about 0.60%. Fine for a rough estimate, not fine for anything you are cutting to size or dosing.
