To convert a measurement in hectopascals to a measurement in millibars, divide the pressure by the following conversion ratio: 1 hectopascals/millibar.

Since one millibar is equal to 1 hectopascal, you can use this simple formula to convert:

millibars = hectopascals ÷ 1

The pressure in millibars is equal to the pressure in hectopascals divided by 1.

For example, here's how to convert 5 hectopascals to millibars using the formula above.
millibars = (5 hPa ÷ 1) = 5 mbar

Hectopascals and millibars are both units used to measure pressure. Keep reading to learn more about each unit of measure.

What Is a Hectopascal?

The hectopascal is equal to 100 pascals, which are defined as the pressure of one newton per square meter. The hectopascal is the internationally adopted unit used to measure atmospheric pressure.

The hectopascal is a multiple of the pascal, which is the SI derived unit for pressure. In the metric system, "hecto" is the prefix for 102. Hectopascals can be abbreviated as hPa; for example, 1 hectopascal can be written as 1 hPa.

What Is a Millibar?

One millibar is equal to one-thousandth of a bar, which is defined as the pressure of one newton per square meter. One millibar is also equal to one hectopascal.

The millibar is a non-SI metric unit for pressure. In the metric system, "milli" is the prefix for thousandths, or 10-3. Millibars can be abbreviated as mbar; for example, 1 millibar can be written as 1 mbar.
