Formula for calculating the weight of steel pipes per meter

Formula for calculating the weight of square tubes:

4 × wall thickness × (Side length wall thickness) × 7.85/1000 kg/m

For example, 50 × 50 ×  4mm square tube weight is: 4 × 4 × (50-4) × 7.85/1000 kg/m=5.77 kg/m

Formula for calculating the weight of rectangular tubes:

2 × (Side length 1+Side length 2- Wall thickness) × wall thickness × length × Density kg/m/1000

For example, 60 × 40 ×  4mm rectangular tube weight is:

2 × (60+40-4) × 4 × 1 × 7.85 kg/m/1000=6.0288 kg/m

Usually, this calculation company calculates a weight that is greater than the actual weight.

There is also a calculation formula for square and rectangular steel pipes:

There is also a formula for calculating the weight per meter for square and rectangular steel pipes:

（2 × (Side length 1+Side length 2)/3.14- Wall thickness) ×  Wall thickness ×  0.0246615 ×  Length/1000

Formula for calculating the weight of circular pipes:

(Outer diameter - wall thickness) ×  Wall thickness × 0.0246615 ×  Length/1000

For example, 2032 ×  40mm round tube weight is:
(2032-40)×40×0.0246615×1/1000=1.96502832 Ton/M
