Rebar Mass from Diameter and Length

rebar mass from diameter and length calculator online

Use rebar mass from diameter and length online for diameter mm, length m, density kg m3. Material-planning geometry only. Supplied dimensions and productivity are scenarios; no structural capacity or building-code compliance is determined.

How to use it

Enter diameter mm. Set length m, density kg m3. Select Calculate and check the labeled output. Copy or download the JSON result.

Options and example settings

Calculation method

mass_kg = pi/4*(diameter_mm/1000)^2*length_m*density_kg_m3 (^ means exponentiation; trig functions ending in d use degrees).

Worked examples

Apply rebar mass from diameter and length to the case below, keeping the displayed units and assumptions. Material-planning geometry only. Supplied dimensions and productivity are scenarios; no structural capacity or building-code compliance is determined.

Choose the right tool

Start with measured net dimensions, then enter supplier coverage, spacing and waste allowances. A material estimate does not determine load capacity, safe construction details or compliance with local building requirements.

Limitations and common mistakes

• Material-planning geometry only. Supplied dimensions and productivity are scenarios; no structural capacity or building-code compliance is determined.
• Use the displayed unit in every field. Ratios and percentages are different inputs; percent fields use values such as 25 rather than 0.25.
