Square Bar Weight Calculator
Solid square steel bar weight per metre and per length (s²/127 rule).
A square bar is 4/π (27%) heavier than the round bar of the same nominal size — the corners aren't free.
Formula
Square Bar Weight Calculator is a free square bar weight for structural engineers, fabricators and site engineers — instant, accurate and 100% client-side, with the governing formula and reference shown next to the result so the number can be defended, not just quoted.
About Square Bar Weight Calculator
Solid square steel bar weight per metre and per length (s²/127 rule). The calculation implements kg/m = s²/127.4 (= s²×7850×10⁻⁶) (IS 2062 density basis). A square bar is 4/π (27%) heavier than the round bar of the same nominal size — the corners aren't free.
