Use the converter below to change any millibars value into torr instantly — with formula, conversion table, and real-world examples.

0.75006

Conversion formula

Forward
torr = millibars × 0.7501
Reverse
millibars = torr × 1.33322

Example: 10 mbar × 0.7501 = 7.50062 Torr.

About both units

From

Millibar

mbar

The millibar equals 100 pascals or 1/1000 bar. It is the traditional unit for atmospheric pressure in meteorology (now called hectopascal, hPa, but numerically identical). Sea-level pressure averages 1013 mbar.

Real-world: Sea-level average: 1013 mbar. Deep low-pressure storm: below 980 mbar. Hurricane eye: below 920 mbar.

Torr

Torr

The torr equals 1/760 atm — approximately 133.32 Pa. Essentially equivalent to mmHg but defined slightly differently. Used in vacuum-system engineering and older physics.

Real-world: Low-vacuum: 760 to 25 torr. High-vacuum: 10⁻³ to 10⁻⁹ torr. Semiconductor fabrication: often below 10⁻⁶ torr.

Tips & common mistakes

Quick tips

  • 1 mbar = 1 hPa = 100 Pa.
  • Weather reports: "1013 hPa" and "1013 mbar" mean the same thing.
  • Hurricane strength correlates with central pressure drop.

Avoid these

  • Confusing mbar and bar — 1000× difference.
  • Using mbar for industrial pressures — too small.
  • Mixing hPa and mbar in casual writing without noting they are equal.

Frequently asked questions

How many torr in a millibar?
One millibar equals 0.7501 torr.
How do I convert millibars to torr?
Multiply the millibar value by 0.7501 to get the equivalent in torr.
What is 100 millibars in torr?
100 millibars equals 75.0062 torr.
Is a millibar bigger than a torr?
No. 1 millibar equals 0.7501 torr, so one millibar is smaller.
How to convert millibars to torr without a calculator?
Multiply by 0.75 for a quick estimate; use a calculator for precise results.
