How we worked it out
Updated as you change the numbers.
- Volume: plate = length × width × thickness; round bar = π/4 × d² × length; tube = π/4 × (OD² − ID²) × length.
- Weight = volume × density.
Method and assumptions
Typical densities; exact alloys vary by a few percent. Carbon steel is about 0.284 lb per cubic inch (490 lb per cubic foot).
Questions
