Convert atmospheres to kilopascals

Explanation

From this page you can convert atmospheres to kilopascals (or atm to kPa) simply, by using the application above.

In case you are wondering, to convert from atmospheres to kilopascals you need to multiply by 101.325. This factor is calculated using the respective definitions of the two units you can find below.

Formula

1 atm=101.325 kPa

atmospheresatm

dimension	pressure
symbol	atm

The standard atmosphere (atm) is a unit of pressure.

It is approximately equal to the atmospheric pressure on Earth at sea level.

Definition of the atmosphere

One standard atmosphere is equal to 101325 Pa.

10^th CGPM (1954) p. 80

History

The standard atmosphere is used during the 9^th CGPM in the definition of the international temperature scale with the value of 1013250 dynes per square centimetre. That definition is reiterated during the 10^th CGPM with the mention "for all use" and the equivalence of 101325 newtons per square meter is added (and as you all know, 1 pascal is equivalent to 1 newton per square meter).

Equivalences

One standard atmosphere is equivalent to:

Some Facts

For every 10 meters you go down under water, the pressure increases by one atm.
Venus's surface atmospheric pressure is more than 90 atm.
The atmospheric pressure at the top of Mount Everest is approximately 0.33 atm.

The kilopascal (kPa) is a unit of pressure.

Definition of the kilopascal

One kilopascal is equal to 1000 pascals.

Equivalences

One kilopascal is equivalent to:

Some Facts

The pressure inside a bottle of champagne is between 400 and 600 kilopascals. It is enough to propel the cork at more than 12 m/s or 27 mph. So be careful.

Prefix

kilo

10³

The prefix kilo- comes from the ancient Greek chilioi meaning thousand. The associated multiplicative factor is 1000 or 10³.

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.
