Hectopascal is a 100x multiple of the Pascal which is the SI unit for pressure. The Hectopascal is the international unit for measuring atmospheric or barometric pressure. 1 Hectopascal equals 100 Pascals.
Due to its low value the Hectopascal is ideal for use as a measure of atmospheric pressure and other low gas pressures such as air flow differentials in air conditioning systems or wind tunnels.
One Hectopascal is exactly equal to One Millibar and although the scientific community has officially adopted the Hectopascal in preference to the Millibar, the Millibar is still used extensively throughout the world due to the proliferation of its use historically.
You can convert a reading in hectopascals into different engineering units by multiplying it by the appropriate conversion factor in the list below.
Alternatively you can let the pressure unit converter do the calculation for you.
