Convert Pascal to Hectopascal

One Pa equals 0.01 hPa. This converter allows you to easily convert between Pascal and Hectopascal in real time.

Formula

Pa × 0.01 = hPa

Example: 1 Pa = 0.01 hPa

What is Pascal?

The pascal is the SI unit of pressure, defined as one newton of force per square meter. Named after French mathematician and physicist Blaise Pascal, it is the foundation for related units like the hectopascal used in weather reports. Since one pascal is a very small amount of pressure, practical applications typically use kilopascals (kPa) or megapascals (MPa). In materials engineering, stress and tensile strength are expressed in megapascals or gigapascals.

What is Hectopascal?

The hectopascal equals 100 pascals and is the standard unit for atmospheric pressure in meteorology worldwide. Standard atmospheric pressure is 1013.25 hPa, and weather reports use hectopascals when describing high and low pressure systems and typhoon central pressures (such as 950 hPa). One hectopascal is exactly equal to one millibar. The international meteorological community switched from millibars to hectopascals in 1992.
