How to Convert Hectopascals to Atmospheres
To convert a measurement in hectopascals to a measurement in atmospheres, multiply the pressure by the following conversion ratio: 0.000987 atmospheres/hectopascal.
Since one hectopascal is equal to 0.000987 atmospheres, you can use this simple formula to convert:
atmospheres = hectopascals × 0.000987
The pressure in atmospheres is equal to the pressure in hectopascals multiplied by 0.000987.
Hectopascals and atmospheres 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 an Atmosphere?
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.
