Total weight
9.81kg
Estimated total steel weight.
Weight per metre
9.81kg/m
Estimated linear weight.
Explanation
What this calculates
The calculator converts the section area from mm2 to m2, then multiplies it by length and density.
Formula
Weight = length x area x density
Inputs are validated on screen and converted where unit options are available.
Worked Example
Example result
A 6 m section with a 1,250 mm2 area weighs about 58.88 kg at 7,850 kg/m3.

Related FAQs
Does this include root radius?
No. Use supplier section tables for final weights.
From Angle Iron Weight Calculator
Can I estimate unequal angle?
Use the material quantity result as a check only; this calculator assumes equal angle.
From Angle Iron Weight Calculator
Does this work for pipe?
It can estimate pipe weight when outside diameter, wall thickness and density are known.
From CHS Weight Calculator
Why might supplier tables differ?
Manufacturing tolerances and rounded section properties can create small differences.

Calculator questions.
What steel density should I use?
A common estimating density for mild steel is 7,850 kg/m3. Check project specifications for specialist alloys.
Can this replace fabrication take-off?
No. Use it for estimating and checks, then verify against drawings, supplier data and contract requirements.
