Calculation formula of steel bar weight Multiply the square of reinforcement diameter (mm) by 0.00617 617 is the weight of round 10 steel bar per meter. The weight of steel bar is proportional to the square of diameter (radius) G=0.617*D*D/100 Weight per meter (kg) = diameter of reinforcement (mm) × diameter of reinforcement (mm) × 0.00617 The density of steel is 7.85 For example, the reinforcement of 10 is 7850 * 0.01/2 square * 3.14 = 0.617kg/m Square of 0.617 * 10 / 100 = 0.617 Other steel bars can be used: 0.00617 * square of steel bar diameter D to calculate the weight per meter But how does this ratio come out, and how can it be justified?

How to deduce the weight of steel bar per meter = 0.00617 D × D (kg)? 1. Steel bar is a cylinder, volume calculation formula: v = π × R × R × L, D: diameter of steel bar (mm), R: radius of steel bar (mm), l: length of cylinder, 1 meter (1000mm), π = 3.1415927, volume of steel bar per meter: v = π × R × R × L = π × D / 2

Round tube, find, weight formula
Round tube, diameter of external aid is 37 mm, diameter of internal aid is 32 mm, length is 1 m, weight and calculation formula are given,

The radius of the outer circle r = 37 / 2 mm = 1.85 cm, the semi longitude of the inner circle r = 1.6 cm, and the length L100 cm,
Volume v = (π r square - π r Square) * l = 270.83 (CC)
In case of steel pipe, the specific gravity of steel is 7.85 g / cm3,
Weight W = V * γ = 270.83 * 7.85 = 2.126 (kg), [4 jin, about 2 liang]
