Explanation: Gauge pressure is the pressure measured relative to atmospheric pressure. The formula for calculating gauge pressure is P = P_abs – P_atm, where P_abs is the absolute pressure and P_atm is the atmospheric pressure. For example, if the absolute pressure is 101 kPa and the atmospheric pressure is 100 kPa, the gauge pressure would be 1 kPa.
