## How to Convert Atmospheres to Hectopascals

To convert an atmosphere measurement to a hectopascal measurement, multiply the pressure by the conversion ratio. One atmosphere is equal to 1,013.25 hectopascals, so use this simple formula to convert:

The pressure in hectopascals is equal to the atmospheres multiplied by 1,013.25.

**For example,**here's how to convert 5 atmospheres to hectopascals using the formula above.

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

## Atmospheres

The atmosphere is a reference measure of pressure equal to 101,325 pascals or 1,013,250 dynes. The atmosphere was originally defined as the pressure of 760 millimeters of mercury at standard gravity at 0 °C, but was later redefined in 1954 to be equal to 1,013,250 dynes.

Atmospheres can be abbreviated as *atm*; for example, 1 atmosphere can be written as 1 atm.

## Hectopascals

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 10^{2}. Hectopascals can be abbreviated as *hPa*; for example, 1 hectopascal can be written as 1 hPa.
