How do you calculate kg of steel?
If we put 1 meter length for each diameter of steel bar in the formula then we will get the unit weight. 6 mm ø bar = 6² x 1/162 = 0.222 kg/m. 8 mm ø bar = 8² x 1/162 = 0.395 kg/m. 10mm ø bar = 10² x 1/162 = 0.617 kg/m. 12mm ø bar = 12² x 1/162 = 0.888 kg/m. 16mm ø bar = 16² x 1/162 = 1.580 kg/m.
How do you calculate steel?
How to Calculate Steel Weight? Weight of Steel = (l/1000) x (w/1000) x t x η l = length in mm. w = width in mm. t = thickness in mm. η = Specific material density ( e.g.: steel = 7.85 kg / dm³).
