Where:

<m>P_s</m> is the system's pressure (or [[absolute pressure]]),

<m>P_{atm}</m> is atmospheric pressure and

<m>P_g</m> is the gauge pressure.

This relationship is shown in Figure 1. Gauge pressure is often used in everyday situations. For example, [[Improving fuel efficiency#Tire pressure|tire pressure]] is measured relative to atmospheric pressure. When a car drives up a mountain the gauge pressure goes up as the atmospheric pressure decreases, but the absolute pressure of the tire remains unchanged assuming the tire does not leak at all.

Gauge pressure should not be used for calculations in the [[ideal gas law]] since it's not a true pressure, but rather a pressure difference.
