bar to mbar Converter - Bar to Millibar
Bar (bar) to Millibar (mbar)
Direct answer
1 bar = 1,000 mbar
mbar = bar × 1,000
Converter
Conversion formula
mbar = bar × 1,000
bar = mbar × 0.001
Example: 10 bar = 10 × 1,000 = 10,000 mbar.

Why the bar-to-mbar conversion factor is 1,000
The conversion factor is derived by expressing both bar and millibar in terms of the same base unit, the pascal. The factor represents the ratio of their definitions in pascals.
Definition
The bar is a metric unit of pressure defined as 100,000 pascals. The millibar is one-thousandth of a bar, defined as 100 pascals.
Principle
Since both units are defined using the pascal, the conversion factor is found by dividing the definition of the source unit by the definition of the target unit. 100,000 Pa per bar divided by 100 Pa per millibar yields the factor of 1,000 millibars per bar.
Assumptions
- The conversion uses the standard definitions of bar and millibar relative to the pascal (SI unit of pressure).
- The factor is exact based on these definitions.
Cautions
- The conversion factor is for the standard bar and millibar units. Always verify the specific definition of 'bar' if used in a non-standard context.
- Result precision should match the requirements of your calculation.
