A miter saw for displaying angle of a cutter blade cutting the workpiece. The miter saw has a base mounting a workpiece thereon, a movable member movably supported to the base, and a cutting unit connected to the movable member for supporting the cutter blade. A positioning portion is associated with the movable member and provides a predetermined nominal position of the movable member with respect to the base. The predetermined nominal position includes a reference position and other positions labeled angle. A detector detects the position of the movable member with respect to the base. A processor sets an angle between the reference position and the predetermined nominal position as a displayed moving amount when the movable member is positioned at the predetermined nominal position. Otherwise, the processor computes the moving amount based on the output signal from the detector.
