How it is calculated
Solid bar cross-section = π × (diameter ÷ 2)². Pipe cross-section = π × wall thickness × (outer diameter − wall thickness) — this is the exact ring-area formula, not an approximation.
Mass per meter = cross-section area (in m²) × metal density. Mass of the whole batch = mass per meter × length.
Density is entered by hand rather than picked from a list of steel grades: the real density of a specific alloy can differ slightly from the reference value, and the calculator should stay accurate for any metal, not just typical carbon steel.
