Estimated total steel weight
106.7 kg
Nominal round-bar formula; verify mill tolerancesHow this calculator helps
Estimate round steel-bar weight from diameter, total length and quantity. Enter measurements and current local quotations from your own project. Material sizes, labour practices, wastage, city prices and legal charges vary, so this transparent result is intended for early budgeting and comparison rather than a final bill of quantities or valuation.
How to use it
- 1
Measure the actual site or use dimensioned drawings rather than visual estimates.
- 2
Enter current local supplier, labour, finance or official charge figures for the required specification.
- 3
Add appropriate wastage and contingency, then have important quantities checked before purchasing or signing.
Formula and methodology
Weight in kg = diameter² ÷ 162 × length in metres × quantity.
Worked calculation example
Ten 12 mm bars, each 12 m long, weigh about 106.7 kg using the common nominal formula.
What can affect the result?
Specification and site
Material grade, structural design, soil, access, workmanship and finish quality can change quantities and cost.
Openings and wastage
Doors, windows, cutting, breakage, laps and usable offcuts must be handled consistently.
Rates and approvals
City prices, taxes, finance offers, valuation rules and transfer charges can change and may depend on status.
Limits of this estimate
This early-stage calculator cannot inspect the site, produce structural design or a bill of quantities, determine legal ownership or valuation, confirm finance approval, or replace an architect, engineer, quantity surveyor, lender or authority.
Frequently asked questions
