hectopascal [hPa] to torr [torr] Converter

Quick Reference

1 hectopascal (hPa) = 0.7500616827 torr (torr)

1 torr (torr) = 1.333223684 hectopascal (hPa)

How to Convert hectopascal to torr

1 hPa = 0.7500616827041697 torr
1 torr = 1.3332236842105263 hPa

To convert hectopascal to torr, divide the value by 1.333223684 (equivalently, multiply by 0.7500616827). To convert torr back to hectopascal, multiply by 1.333223684.

Example: convert 10 hPa to torr:
10 hPa = 10 x 0.7500616827041697 = 7.500616827041697 torr

↔ Convert torr to hectopascal

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.

torr

Definition: The torr (symbol: Torr) is a unit of pressure defined as 1/760 of a standard atmosphere. It is named after Evangelista Torricelli, an Italian physicist and mathematician.

History/origin: The torr is based on the pressure exerted by a column of mercury 1 millimeter high. It was originally defined in relation to the height of a mercury barometer.

Current use: The torr is used in vacuum technology, pressure measurement of low-pressure systems, and some areas of scientific research.
