A method of measuring an effective heating power applied to a workpiece at a position to be heated by a high frequency heating apparatus having a source of high frequency AC power connected to a resonant circuit having a supply of high frequency AC power from the source for applying a high frequency AC power to the workpiece. An effective power PHF for the power supplied to the resonance circuit is measured. An effective value It for the current sensed in the resonance circuit is measured. A power loss W produced in components following the source is calculated as a function of the measured effective value It. The effective heating power Pw is calculated as PW = PHF - W.
