What is Hectopascal?

Hectopascal is a pressure unit used to express mechanical, atmospheric or process pressure values.

Short history of Hectopascal

The hectopascal equals the millibar. Meteorology adopted it in the late 20th century because it keeps weather-map values unchanged: standard sea-level pressure is 1013.25 hPa.

What is Pascal?

The pascal is the SI derived unit of pressure. It is defined by the relationship 1 Pa = 1 N/m².

Short history of Pascal

Named after Blaise Pascal, the unit became the standard SI reference for pressure across science and engineering.
