build.steel-weight Calculator
Calculates the weight of structural steel sections (W-shapes, HSS, rebar) from diameter or section profile and length, in both imperial and metric. Steel weight directly determines erection cost (crane capacity, rigging) and material cost in fabricated assemblies.
Inputs
L
Linear measurement. Ensure consistent units: 1 m = 1,000 mm = 3.281 ft.
Dia
Distance across a circle through its centre. Always confirm units match the rest of the calculation.
Qty
Count or number of items involved.
Price
Reference formula or conversion factor shown for context.
Results
weight/bar (kg)
The computed weight (gravitational force) or mass.
total weight (kg)
The computed weight (gravitational force) or mass.
tonnes
Sample size or count used in the calculation.
material cost
The total monetary cost computed for the given inputs.
wt/m (kg/m)
Reference formula or conversion factor shown for context.
rule: d²/162 kg/m
Reference formula or conversion factor shown for context.
