# Some commonly used formulas for calculating the weight of metal materials

Some commonly used formulas for calculating the weight of metal materials
In all the following units, the length is mm, and the weight is g.
1. Steel bar weight (grams) = 0.00617 × diameter × diameter × length
Example: The following is a round bar with a diameter of 8.0MM and a length of 100MM.
Its weight is.

• 0.00617*8*8*100=39.488g

(i.e. 0.039488KG, with the current unit price of 4.6 yuan/kg, the price of the round bar material is 0.0039488*4.6=0.18 yuan).
The following and so on, no more examples:

• 2. Hexagonal steel weight (g) = 0.0068 × width of the opposite side × width of the opposite side × length
• 3. Square steel weight (g) = 0.00785 x side width x side width x length
• 4. Weight of octagonal steel (g) = 0.0065 × width of the opposite side × width of the opposite side × length
• 5. Rebar weight (g) = 0.00617 × calculated diameter × calculated diameter × length
• 6. Angle weight (g) = 0.00785 × (side width + side width – side thickness) × side thickness × length
• 7. Flat steel weight (g) = 0.00785 × thickness × side width × length
• 8. Steel pipe weight (g) = 0.02466 × wall thickness × (outside diameter – wall thickness) × length
• 9. Steel plate weight (g) = 7.85 × thickness × area
• 10. Copper round bar weight (g) = 0.00698 × diameter × diameter × length
• 11. Brass round bar weight (g) = 0.00668 × diameter × diameter × length
• 12. Aluminum round bar weight (g) = 0.0022 × diameter × diameter × length
• 13. Copper square bar weight (g) = 0.0089 × side width × side width × length
• 14. Brass square bar weight (g) = 0.0085 x side width x side width x length
• 15. Aluminum square bar weight (g) = 0.0028 x side width x side width x length
• 16. Hexagonal copper bar weight (g) = 0.0077 x side width x side width x length
• 17. Hexagonal brass bar weight (g) = 0.00736 x side width x side width x length
• 18. Hexagonal aluminum bar weight (g) = 0.00242 × width of the opposite side × width of the opposite side × length
• 19. Copper plate weight (g) = 0.0089 × thickness × width × length
• 20. Brass plate weight (g) = 0.0085 × thickness × width × length
• 21. Aluminum plate weight (g) = 0.00171 × thickness × width × length
• 22. Copper round tube weight (g) = 0.028 × wall thickness × (outside diameter – wall thickness) × length
• 23. Brass round weight (g) = 0.0267 × wall thickness × (outside diameter – wall thickness) × length
• 24. Aluminum round tube weight (g) = 0.00879 × wall thickness × (outside diameter – wall thickness) × length
