Steel Bar Weight Calculator | NexUtils
Steel Bar Weight
Calculate weight of reinforcement steel.
Std bar = 12m
Select Diameter & Length
About This Tool
In construction billing, steel is measured by weight, but ordered by length (bundles). The Steel Bar Weight Calculator helps you verify the theoretical weight of TMT bars using the standard engineering formula (D²/162). Whether you are purchasing 8mm stirrups or 25mm column bars, this tool instantly tells you the weight per meter and the total weight of the bundle. It's an essential tool for site engineers and supervisors to check if the supplied steel matches the billed weight. This tool has become indispensable for construction professionals across India, from small contractors to large construction firms. It accounts for industry-standard specifications and local building codes, ensuring your estimates are accurate and reliable. The calculator helps prevent costly mistakes like material shortages mid-project or excessive wastage that impacts your budget. Whether you're bidding on a project, planning a renovation, or managing a large construction site, this tool provides the precision you need for successful project execution. It saves hours of manual calculations and reduces the risk of human error in critical construction planning. Our algorithms are optimized for performance, ensuring instant results even for complex calculations. We are committed to providing free, high-quality tools to help you be more productive.
How to Use This Tool
Select Diameter
Choose standard sizes (8mm, 10mm, 12mm, 16mm, etc.).
Enter Length
Input the length of bars in meters or feet.
Quantity
Enter the number of bars or bundles.
Calculate
Get total weight in Kilograms (kg) and Tonnes.
Key Features
- Verification: Cross-check weighing bridge slips against theoretical weight.
- Standard Formula: Uses D²/162.2 for precise kg/m calculation.
- Bundle Estimation: Calculate total weight for hundreds of bars.
- Cost Estimation: Convert weight to cost based on current steel prices.
Frequently Asked Questions
What is the formula for steel weight?
Weight (kg/m) = (Diameter in mm)² / 162.2. For example, for 10mm rod: 100/162.2 = 0.617 kg/m.
Why do actual weights differ?
IS codes allow a small rolling margin tolerance (±3-5%). If the difference is huge, the steel might be underweight (sub-standard).
