Calculation rule, particularly applicable to the calculation and use of copper electrical conductors, characterized in that, it consists of a slide on which a wrapper slider-falsilla slides tightly, carrying the printed strip on its two faces numerical series referring to dimensions and characteristics of the conductors, while the cursor that surrounds it in the form of an envelope, has windows made so that, on both sides, it appears, or appears, depending on whether it is data or unknowns, the corresponding values of the problem that interests at every moment.
