hectopascal [hPa] to bar [bar] Converter
How to Convert hectopascal to bar
1 hPa = 0.001 bar
1 bar = 1000 hPa
Example: convert 10 hPa to bar:
10 hPa = 10 x 0.001 = 0.01 bar
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.
bar
Definition: The bar (symbol: bar) is a metric unit of pressure, but not part of the International System of Units (SI). It is defined as exactly equal to 100,000 Pa (100 kPa), which is slightly less than current average atmospheric pressure on Earth at sea level.
History/origin: The bar was introduced by British meteorologist William Napier Shaw in 1909.
Current use: The bar is used in various fields, including meteorology, diving (for measuring pressure underwater), and industrial applications. It is often used when a unit close to atmospheric pressure is convenient.
