Hectopascals to Pascals converter

To convert hectopascals to pascals, enter the value in the first field. The result in pascals is calculated automatically using the exact conversion factor.

1 hPa = 100 Pa
1 Pa = 0.01 hPa

Formula: Pa = hPa × 100
hPa = Pa × 0.01

Definitions: 1 hPa = 100 Pa

The hectopascal (hPa) equals 100 pascals and is exactly the same as one millibar. It is the unit weather services use for atmospheric pressure, with average sea-level pressure around 1013 hPa.

The pascal (Pa) is the SI unit of pressure, one newton per square meter. It is a very small unit, so everyday pressures are usually given in kilopascals or hectopascals, but the pascal is the base of physics, acoustics and engineering formulas.
