Convert 2200 psi to atmospheres

Explanation

Let's convert 2200 pounds per square inch to atmospheres, or psi to atm as one could put it.

First, we need to calculate the conversion factor using the units respective values. We find 0.06805.

Then we multiply this conversion factor by the number of pounds per square inch. In this case 2200.

Therefore, 2200 pounds per square inch is approximately equal to 149.7011 atmospheres.

Formula

1 psi≈0.06805 atm

2200 psi≈2200 × 0.06805 atm

2200 psi≈149.7011 atm

The pound per square inch (psi, lbf/in²) or psi is a unit of pressure.

The "pound" in "pound per square inch" is the pound-force, not to be confused with the pound the unit of mass. One pound-force is the force exerted downward by a mass of one avoirdupoids pound on the surface of the Earth.

Definition of the pound per square inch

One psi is equal to the pressure exerted by a force of one pound-force on a surface of one square inch.

Equivalences

One psi is equivalent to:

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.
