Did You Know?

At sea level, 1 atmosphere (atm) is 14.7 psi—the weight of Earth’s air pressing down on you!

The deepest ocean point (Mariana Trench) has 1,086 bars of pressure—equivalent to 50 jumbo jets stacked on you.

Blood pressure is measured in mmHg because early devices used mercury columns.
