A gauge system determines the thread pitch diameter of an internally or externally-threaded article and includes a standard measuring caliper with styli selected and fitted into the caliper to correspond to a particular thread type and pitch. The styli are mounted into the caliper to provide a reference zero position to the calipers for either externally or internally-fitted articles. A processor is associated with the calipers and styli and is of a type which is configured for hand-holding. The processor has input buttons for inputting a descriptor of internal or external threads, thread type and thread pitch. The processor software receives and processes information received from the caliper to calculate the thread pitch diameter. A display connected to the processor presents the thread pitch diameter.
