A hectopascal is a unit used to measure 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.

How Much 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.

How to Convert Hectopascals

To convert hectopascals to another unit of pressure, you need to multiply the value by a conversion factor. A conversion factor is a numerical value used to change the units of a measurement without changing the value.[1]

You can find the conversion factors for hectopascals in the conversion table below.

Then, multiply the pressure measurement by the conversion factor to find the equivalent value in the desired unit of measurement.

hectopascals × conversion factor = result

You can also use a calculator, such as one of the converters below, for the conversion.
