1. Square bar (plate): (side length mm x side length x specific gravity x length) ÷ 1000000=kg

2. Round cake (bar): (diameter mm x diameter x 0.7854 x specific gravity x length) ÷ 1000000=kg

3. Ring and pipe: (outer diameter inner diameter) ÷ 2=wall thickness

(Outer diameter wall thickness) x Wall thickness x 3.14 x Specific gravity x Height ÷ 1000000=kg
