Convert bar to millibar

Please provide values below to convert bar [bar] to millibar [mbar], or Convert millibar to bar.

1 bar = 1000 mbar. To convert bar to millibar, multiply the value by 1000; to go the other way, divide by it (1 mbar = 0.001 bar). Both units measure pressure and appear in everyday as well as technical calculations, so switching between them quickly is often useful.

Quick Reference

  • 1 bar = 1000 mbar
  • 1 mbar = 0.001 bar
  • 10 bar = 10000 mbar
  • 100 bar = 100000 mbar



How to Convert Bar to Millibar

1 bar = 1000 mbar

Example: convert 15 bar to mbar:
15 bar = 15 × 1000 mbar = 15000 mbar

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.


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.


Frequently Asked Questions

What is 1 bar in millibar?

1 bar (bar) = 1000 millibar (mbar).

How do you convert bar to millibar?

Multiply the bar value by 1000. For example, 25 bar × 1000 = 25000 mbar.

What is 10 bar in millibar?

10 bar = 10000 mbar.

Which unit is larger, the bar or the millibar?

The bar is the larger unit: 1 bar = 1000 mbar.
