Available: http://www.convertunits.com/info/psig</ref> The unit to measure psig is '''[[psi]]'''.

	For example, a bike tire may be 65 psi above atmospheric pressure which is its psig value, and if the atmospheric pressure is 14.7 psi, then its psia value would be 65 + 14.7 = 79.7 psia.		In contrast to psig, '''''psia''''' is '''[[psi\|pounds per square inch absolute]]''' and it measures the [[absolute pressure]], which is gauge pressure plus atmospheric pressure. This means it is measured with respect to [[vacuum]].

			All of this can be visualized in Figure 1.

			For example, a bike tire may be 65 psi above atmospheric pressure, which is its psig value, and if the atmospheric pressure is 14.7 psi, then its psia value would be 65 + 14.7 = 79.7 psia.
