Convert 15 bars to atmospheres

Explanation

Let's convert 15 bars to atmospheres, or bar to atm as one could put it.

First, we need to calculate the conversion factor using the units respective values. We find 0.9869.

Then we multiply this conversion factor by the number of bars. In this case 15.

Therefore, 15 bars is approximately equal to 14.8038 atmospheres.

Formula

1 bar≈0.9869 atm

15 bar≈15 × 0.9869 atm

15 bar≈14.8038 atm

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 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.
