The SI derived unit for **pressure** is the pascal.

1 pascal is equal to 0.000145037738007 psig, or 1.01971621298E-5 atmosphere [technical].

Note that rounding errors may occur, so always check the results.

I'm feeling lucky, show me some random units.

Psig (pound-force per square inch gauge) is a unit of pressure relative to the surrounding atmosphere. By contrast, psia measures pressure relative to a vacuum (such as that in space). At sea level, Earth's atmosphere actually exerts a pressure of 14.7 psi. Humans do not feel this pressure because internal pressure of liquid in their bodies matches the external pressure. If a pressure gauge is calibrated to read zero in space, then at sea level on Earth it would read 14.7 psi. Thus a reading of 30 psig on a tire gauge represents an absolute pressure of 44.7 psi.
