Convert microbar to bar
Please provide values below to convert microbar [µbar] to bar [bar], or Convert bar to microbar.
1 µbar = 1e-06 bar. To convert microbar to bar, multiply the value by 1e-06; to go the other way, divide by it (1 bar = 1000000 µbar). Both units measure pressure and appear in everyday as well as technical calculations, so switching between them quickly is often useful.
Quick Reference
- 1 µbar = 1e-06 bar
- 1 bar = 1000000 µbar
- 10 µbar = 1e-05 bar
- 100 µbar = 0.0001 bar
How to Convert Microbar to Bar
1 µbar = 1e-06 bar
Example: convert 15 µbar to bar:
15 µbar = 15 × 1e-06 bar = 1.5e-05 bar

Microbar
A microbar (µbar) is a unit of pressure equal to one millionth of a bar, where 1 bar equals 100,000 pascals.
History/Origin
The microbar was introduced as a subunit of the bar to measure very low pressures, particularly in meteorology and vacuum technology, gaining usage in the 20th century as precision pressure measurements became more common.
Current Use
Today, the microbar is used primarily in meteorology for measuring atmospheric pressure variations and in scientific research requiring precise low-pressure measurements.
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 microbar in bar?
1 microbar (µbar) = 1e-06 bar (bar).
How do you convert microbar to bar?
Multiply the microbar value by 1e-06. For example, 25 µbar × 1e-06 = 2.5e-05 bar.
What is 10 microbar in bar?
10 µbar = 1e-05 bar.
Which unit is larger, the microbar or the bar?
The bar is the larger unit: 1 µbar equals only 1e-06 bar.
