Convert hectopascals to bars

Explanation

From this page you can convert hectopascals to bars (or hPa to bar) simply, by using the application above.

In case you are wondering, to convert from hectopascals to bars you need to multiply by 0.001. This factor is calculated using the respective definitions of the two units you can find below.

Formula

The hectopascal (hPa) is a unit of pressure.

One hectopascal is equal to a millibar, this explains why this unit is used in meteorology for atmospheric pressure when integer powers of 1000 are prefered in almost all other fields of science.

Definition of the hectopascal

One hectopascal is equal to 100 pascals.

Equivalences

One hectopascal is equivalent to:

Prefix

hecto

10²

The prefix hecto- comes from the Greek hekatón meaning a hundred. The associated multiplicative factor is 100 or 10².

The International System of Units

The International System of Units or SI (from the French Système international (d'unité)), also called metric system in the U.S., is a coherent system of units that was published 1960. It is official in nearly every country.

The General Conference on Weights and Measures (Conférence générale des poids et mesures) is tasked with overseeing the SI.

The bar (bar) is a metric unit of pressure not part of the SI.

The unit is most prominently used in meteorology to express atmospheric air pressure with values generally in millibars.

One bar is roughly equal to the average atmospheric pressure at sea level on Earth.

Definition of the bar

One bar is equal to 100000 pascals.

Some Facts

The atmospheric pressure at the surface of Venus is 92 bars, at this pressure the boiling point of water is more than 300 °C (or 572 ° F). Teatime must be quite peculiar on Venus.
