FAQ
How is metal weight calculated?
Weight = cross-sectional area × length × density. The area is computed per shape (round πr², tube outer minus inner, plate thickness × width), then multiplied by length and material density. For example, a 10 mm round steel bar weighs about 0.617 kg per meter.
What densities are used?
Steel (SS) 7.85, stainless (STS) 7.93, aluminum 2.70, brass 8.50, copper 8.96, zinc 7.14 g/cm³.
How do I get square tube weight?
For a square/rectangular tube, subtract the inner hollow area from the outer area, then multiply by length and density. Enter width, height and wall thickness and it calculates automatically.
