PURPOSE: A system and method for calibrating pressure gauge is provided to achieve improved user convenience and reduced error, while shortening time taken for obtaining calibration records and result by permitting the process for making calibration records to be automatically performed. CONSTITUTION: A pressure gauge calibration method, comprises a first step(S110) of inputting initial parameters including information on a standard and an object for calibration and calibration range; a second step(S120) of inputting other parameters required for calibration; a third step(S130,S140) of calculating standard weight list to be used in a pressure calibration range; a fourth step(S150,S160) of selecting one from a deadweight type calibration or a non-deadweight type calibration; a fifth step(S170) of automatically calculating parameters required for deadweight type calibration when the deadweight type calibration is selected and additional parameters are input; a sixth step(S180) of calculating relation between the pressure value of standard and output value of an object for calibration by analyzing all information, and calculating uncertainty; and a seventh step(S190) of outputting calibration records and result in accordance with the uncertainty calculated in the sixth step.
