Our interactive web-based tool enables you to accurately compute the weight of carbon steel rebar. Simply input the desired bar length and choose the nominal diameter (ranging from 6 mm to 80 mm); our dual-function calculator then lets you determine either the weight per meter or the total mass of the rebar according to your specifications. This comprehensive rebar weight calculator is indispensable for project estimation, structural evaluation, and even cost calculations—whether priced per meter or per tonne.
With knowledge of the nominal diameter and material density, you can manually compute the rebar weight. The calculation is based on the formula m = (D² * Pi / 4) * ρ, which relates the weight of one meter of rebar to the area of a circle with the same diameter. Key parameters include:
The standard density of carbon steel rebar is 7850.00 kg/m3.
While our reference tables and online calculator offer theoretical weight values, real-world rebar may exhibit slight dimensional deviations from the nominal values. To determine the actual weight, it is advisable to measure the rebar over a specified length. Detailed information regarding the rebar’s weight and specifications can be referenced in the manufacturer’s certificate.
In construction and installation projects, accurate weight estimation of metal components is crucial. It ensures the structural parameters are validated and material costs are estimated correctly (for example, by evaluating the weight of 10 mm rebar per meter). Comprehensive tables listing rebar parameters along with precise online calculators are essential tools for these assessments.
Knowing the exact weight of rolled materials can yield significant savings by ensuring the optimal transportation solution is selected.
Our online rebar weight calculator provides a quick and precise way to determine the weight of rebar. Whether you need to calculate the weight for varied diameters such as 8 mm, 10 mm, or 12 mm, simply input the relevant data. For convenience, the tool also displays a table showing the weight per meter for each diameter. Use the calculation formula to verify the weight values for your chosen rebar size.
Calculating rebar weight has never been easier! Utilize our service for accurate and efficient computations—whether determining weight by length or overall mass.
