Convert millibar to bar
Please provide values below to convert millibar [mbar] to bar [bar], or Convert bar to millibar.
1 mbar = 0.001 bar. To convert millibar to bar, multiply the value by 0.001; to go the other way, divide by it (1 bar = 1000 mbar). Both units measure pressure and appear in everyday as well as technical calculations, so switching between them quickly is often useful.
Quick Reference
- 1 mbar = 0.001 bar
- 1 bar = 1000 mbar
- 10 mbar = 0.01 bar
- 100 mbar = 0.1 bar
How to Convert Millibar to Bar
1 mbar = 0.001 bar
Example: convert 15 mbar to bar:
15 mbar = 15 × 0.001 bar = 0.015 bar

Millibar
A millibar (mbar) is a unit of pressure measurement equal to one-thousandth of a bar, commonly used in meteorology to measure atmospheric pressure.
History/Origin
The millibar was introduced in the early 20th century as a convenient unit for meteorological measurements, replacing the bar in many applications due to its smaller size. It became widely adopted in weather reporting and atmospheric studies.
Current Use
Today, the millibar is still used in meteorology and atmospheric sciences to report atmospheric pressure, although it is gradually being replaced by the Pascal (Pa) in scientific contexts. It remains a standard unit in weather forecasts and reports.
Bar
The bar is a unit of pressure equal to 100,000 pascals, roughly the atmospheric pressure at sea level.
History/Origin
The bar was introduced in 1909 by the British engineering community as a convenient unit for measuring pressure, especially in meteorology and engineering contexts.
Current Use
The bar is widely used in meteorology, engineering, and industrial applications to measure pressure, although the pascal is the SI base unit. It is also common in tire pressure measurements and other pressure-related fields.
Frequently Asked Questions
What is 1 millibar in bar?
1 millibar (mbar) = 0.001 bar (bar).
How do you convert millibar to bar?
Multiply the millibar value by 0.001. For example, 25 mbar × 0.001 = 0.025 bar.
What is 10 millibar in bar?
10 mbar = 0.01 bar.
Which unit is larger, the millibar or the bar?
The bar is the larger unit: 1 mbar equals only 0.001 bar.
