hectopascal [hPa] to kilopascal [kPa] Converter

Quick Reference

1 hectopascal (hPa) = 0.1 kilopascal (kPa)

1 kilopascal (kPa) = 10 hectopascal (hPa)

How to Convert hectopascal to kilopascal

1 hPa = 0.1 kPa
1 kPa = 10 hPa

To convert hectopascal to kilopascal, divide the value by 10 (equivalently, multiply by 0.1). To convert kilopascal back to hectopascal, multiply by 10.

Example: convert 10 hPa to kPa:
10 hPa = 10 x 0.1 = 1 kPa

↔ Convert kilopascal to hectopascal

hectopascal

Definition: The hectopascal (symbol: hPa) is a multiple of the pascal, which is the SI unit of pressure. One hPa is equal to 100 pascals.

History/origin: The hectopascal was introduced as a replacement for the millibar (mbar) in meteorology. The change was intended to promote the use of SI units.

Current use: Hectopascals are primarily used in meteorology for measuring atmospheric pressure. 1 hPa is equivalent to 1 mbar, which was previously the standard unit for atmospheric pressure.

kilopascal

Definition: The kilopascal (symbol: kPa) is a multiple of the pascal, which is the SI unit of pressure and stress. One kPa is equal to 1000 pascals.

History/origin: Like the pascal, the kilopascal's origin is tied to the development of SI units. It provides a more convenient scale for expressing pressures larger than a single pascal.

Current use: Kilopascals are widely used in engineering, construction, and meteorology for measuring air pressure, fluid pressure, and mechanical stress.
