2" x 2" x 0.1875" cast iron angle weighs 2.230 lb per ft (3.32 kg per m). Weight = cross-section area x length x 0.26 lb per cubic inch.
How much does cast iron angle weigh per foot?
| Size | Area (sq in) | lb per ft | kg per m | 12 ft length, lb |
|---|---|---|---|---|
| 1" x 1" x 0.125" | 0.2344 | 0.731 | 1.09 | 8.8 |
| 1.25" x 1.25" x 0.125" | 0.2969 | 0.926 | 1.38 | 11.1 |
| 1.5" x 1.5" x 0.125" | 0.3594 | 1.121 | 1.67 | 13.5 |
| 1.5" x 1.5" x 0.1875" | 0.5273 | 1.645 | 2.45 | 19.7 |
| 2" x 2" x 0.1875" | 0.7148 | 2.230 | 3.32 | 26.8 |
| 2" x 2" x 0.25" | 0.9375 | 2.925 | 4.35 | 35.1 |
| 3" x 3" x 0.25" | 1.4375 | 4.485 | 6.67 | 53.8 |
| 4" x 4" x 0.375" | 2.8594 | 8.921 | 13.28 | 107.1 |
Formula: area = thickness x (leg A + leg B minus thickness); weight = area x length x 0.26 lb/in3. Corner radii are ignored, so real stock runs one to three percent lighter than the table. For any other size use the metal weight calculator.

Frequently asked questions
How do you calculate the weight of cast iron angle?
Multiply the cross-section area in square inches by the length in inches and by the density, 0.26 lb per cubic inch for cast iron (gray, class 30). For this shape the area is: area = thickness x (leg A + leg B minus thickness). A foot of stock is 12 inches, so weight per foot is area x 12 x 0.26.
How does cast iron compare with steel by weight?
Cast iron is 8% lighter than carbon steel for the same size: 0.26 lb per cubic inch against 0.2836. The same bar or plate in cast iron weighs 0.92 times the steel figure.
