How to Convert Millibar to Torr

To convert Millibar to Torr, multiply mbar by 0.750062 because 1 mbar ≈ 0.750062 Torr.

Conversion Formula:

value * 0.750062

Understanding the Conversion

Millibar to Torr connects atmospheric-style units to the vacuum-oriented Torr scale. Multiply mbar by 0.750062. For example, 1,013.25 mbar ≈ 760 Torr (atmosphere). Useful when vacuum specs or gauges are given in Torr but source data is in mbar/hPa.

Conversion Examples

Example: Convert 1,013.25 mbar to Torr

Step 1: 1,013.25 × 0.750062 ≈ 760.
Step 2: Result ≈ 760 Torr.
Step 3: Atmospheric reference.

1,013.25 mbar ≈ 760 Torr

Sea-level pressure in Torr.

Example: Convert 500 mbar to Torr

Step 1: 500 × 0.750062 ≈ 375.03.
Step 2: Result ≈ 375 Torr.
Step 3: Midrange example.

500 mbar ≈ 375 Torr

Sub-atmospheric level.

Example: Convert 50 mbar to Torr

Step 1: 50 × 0.750062 ≈ 37.5.
Step 2: Result ≈ 37.5 Torr.
Step 3: Shows low pressure.

50 mbar ≈ 37.5 Torr

Low absolute pressure scenario.

Conversion Formula

1 mbar is 100 Pa; 1 Torr is about 133.322 Pa. Multiplying mbar by 100/133.322 gives the 0.750062 factor.

Unit Definitions

Millibar (mbar)

Atmospheric unit.

1 mbar ≈ 0.750062 Torr = 0.1 kPa = 100 Pa.

Torr (Torr)

Vacuum unit (1/760 atm).

Torr to mbar divide by 0.750062; Torr to kPa divide by 7.50062; Torr to Pa multiply by 133.322.

Common Use Cases

Vacuum and lab reporting in Torr
Semiconductor/process specs in Torr
Education linking mbar/hPa to Torr
Calibration between mbar sensors and Torr gauges

Frequently Asked Questions

Why convert to Torr?

Vacuum specs and gauges often use Torr; converting keeps communication clear.

Is the factor constant?

Yes, based on the defined relation between atmosphere, Pa, and Torr.

How to revert?

Divide Torr by 0.750062 to return to mbar.
