Frequently asked questions
What is the source unit in this conversion?
The source unit is the millibar (mbar). A millibar is 100 pascals.
What is the destination unit in this conversion?
The destination unit is the bar (bar). A bar is exactly 100,000 pascals.
How do I convert millibar to bar?
Multiply the millibar value by 0.001. For example, 10 mbar × 0.001 = 0.01 bar.
Is the millibar to bar conversion exact?
Yes. Both units are defined as fixed multiples of the pascal, the SI-derived unit of pressure, so the conversion factor follows directly from those exact definitions rather than a measured approximation.
Where is this conversion commonly used?
It's used whenever a value expressed in millibar needs to be compared with, or reported in, bar, such as in engineering specifications, weather readings, tire pressure, or industrial and scientific work.
Can I convert bar back to millibar?
Yes. Multiply the bar value by 1000 to get millibar.

About this conversion
This page converts millibar (mbar) to bar (bar) within the pressure converter.
A millibar is 100 pascals. A bar is exactly 100,000 pascals.
The formula is bar = millibar × 0.001, based on each unit's fixed relationship to the pascal, the pressure converter's base unit.
The conversion is exact, since both units are tied to the pascal by a fixed numerical ratio rather than a measured or approximate value.
