Pounds per square inch to atmospheres
Type a value in psi to get it in atm instantly.
That's 2× as much pressure as the air on Everest, while air at sea level is 1.47× higher. Spread over a fingertip, that is like resting 0.7031 kg on it.
Convert the other way: atm to psi
What it means
How much pressure is that?
Tyre and tank figures are gauge pressure, measured above the surrounding air. Weather and altitude figures are absolute.
The math
How to convert psi to atm
To convert pounds per square inch to atmospheres, multiply by 0.068046.
Example: 10 psi × 0.068046 = 0.68046 atm.
In the other direction, 1 atm = 14.6959 psi.

The units
About these units
Pounds per square inch (psi)
One psi is one pound of force on one square inch, about 6,895 pascals. US tyre gauges, compressors and plumbing all read in psi.
Atmospheres (atm)
One standard atmosphere is defined as exactly 101,325 pascals: the average air pressure at sea level. Diving depth adds about one atmosphere every 10 meters.
