To convert a measurement in hectopascals to a measurement in bars, divide the pressure by the following conversion ratio: 1,000 hectopascals/bar.

Since one bar is equal to 1,000 hectopascals, you can use this simple formula to convert:

bars = hectopascals ÷ 1,000

The pressure in bars is equal to the pressure in hectopascals divided by 1,000.

For example, here's how to convert 500 hectopascals to bars using the formula above.
bars = (500 hPa ÷ 1,000) = 0.5 bar

Hectopascals and bars 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 Bar?

The bar is equal to 100,000 pascals, which are defined as the pressure of one newton per square meter. One bar is just less than the average atmospheric pressure.

The bar is a non-SI metric unit for pressure. Bars can be abbreviated as bar; for example, 1 bar can be written as 1 bar.
