Convert one bar to pascals

Explanation

To convert one bar to pascals all we need is to know the conversion factor and we are done. Luckily, we can compute that factor using the units' definitions below.

We find that one bar is equal to 100000 pascals.

Formula

1 bar = 100000 Pa

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.

Equivalences

One bar is equivalent to:

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.

The pascal (Pa) is the derived SI unit of pressure.

Definition of the pascal

One pascal is the pressure exerted by a force of one newton on a surface of one square meter.

The pascal is homogeneous to kilogram per meter per second squared.

Pa = N m^-2 = kg m⁻¹ s⁻²

Equivalences

Here are some equivalences between the pascal and other pressure units:

Some Facts

The pascal is quite a small unit. A common housefly laying flat on your hand would apply a pressure of approximately 8 pascals.

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.
