A self-adjusting balance comprising a stirrup supporting a rotatable disk at its center. The front face of the disk is graduated in degrees from 0 DEG to 90 DEG , the graduations continuing on the reverse face from 90 DEG to 0 DEG . At the rim of the disk there are two slots, at diametrically opposite 0 DEG marks, to accommodate cords, one to be connected to a weight to be measured and the other to a standard weight, the weight to be measured being connected to the cord in the front face 0 DEG slot with the cord lying circumferentially against a portion of the rim of the disk to the point where this cord hangs free and vertical, the standard weight being connected to the cord in the diametrically opposite slot, this cord hanging free and vertical.
