A hand tool with twisting force measuring functions comprises a driving portion having a driving head for screwing a screwing elements; a handle connected to the driving portion; the handle including a first lateral side and a second lateral side adjacent to the first lateral side; at least strain gauge installed in the first lateral side; at least one strain gauge installed in the second lateral side; an integrating element installed on the handle for calculating twisting forces of the tool body by measuring data from the strain gauges of the first and second lateral sides. The strain gauge in the first lateral side and second lateral side are connected with other circuit element as a Wheaston Bridge for measuring twisting force of the hand tool. The Wheaston bridge of the first lateral side is connected across one element of the Wheaston bridge of the second lateral side.
