Metal calculator calculates the mass and the surface area of the steel rolled metal. Two calculation modes are implemented: 1. Calculation of the mass of the steel profile for a given length; 2. Calculation of the color area of the steel profile for a given mass. Everything is reduced to a table with the definition of the total values of weight and area of color. Calculation of the weight of steel is available in metric and British units. The results of calculations can be saved. In the calculat
