  • To Mass Weight in Kg

    Hai.
    I have steel plate with the following details : 1200mm x 1400mm x 12mm thickness. How to convert to weight?.

    the density of plain mild steel is 7.85.
    the long answer is that depending on where you look, or the grade of steel that you are talking about can change this value. a density of 7.88 is often quoted for mild steel as well. if you add alloying elements such as tungsten, chrome or manganese to improve the steel, the density will change. so the long answer is that the density of steel can vary between
    7.75 and 8.05.

    To calculated the mass of steel, you can work on the basis that steel
    weighs 7.88mg/mm3, So...
    a) 1 mg of steel is 1/7.88 = 0.126 903 553 299 492 385 786 802 030 456 85 mm3.
    b) To calculate the mass of a steel plate, take the dimensions in millimeters
    and then, width x thickness x length x 7.88 = milligrams of steel. multiply that by 1 000 and you get grams, multiply the result in grams by 1 000 and you get kilograms

      Hi, I think gubment_cheez means use millimeters, not use inches.

      To get weight, multiply the volume by the density. In this case, the density is about 7.88, the volume is easiest to deal with in cubic cm.

      volume in cubic cm: 140 x 120 x 1.2 = 20,160 cubic cm

      weight in grams: 20160 x 7.88 = 158,861g

      weight in kg = 159kg

        yeah, when I originally wrote it out, the values were in lbs/f3, I converted that into inches, when I originally wrote that text, then I realized the question was in millimeters, so I converted it into milimeters. I forgot to change that word

            1.2 m x 1.8 m x 0.012 m = 0.0259 m
            at 7850 kg/m, 203.5 kg
            Note the density will vary slightly according to the exact grade of steel you have.

                      You can calculate the weight of common shapes in copper steel, brass and many other materials, in inches or mm, to get kg or pounds at

                      machined-castings.com/calc.html

                      This is the most complete and flexible steel weight calculator that I have seen online.

                          1.2 meter x 1.4 meter x 7.85 x 12mm thickness =158.256 kgs

                            Ans:
                            1200*1400*12

                            Use the formula of plate : L*B*T*0.00000785

                            1200*1400*12*0.00000785 = 158.250
