How the Steel Quantity Calculator Works
This tool helps you estimate the total weight of steel rebar quickly. Here’s a simple breakdown of its operation:
Input & Calculation: You provide three key values: the length of each bar (in meters), the number of bars, and the weight per meter (kg/m) for the specific rebar size. When you click the "Calculate Steel" button, the tool multiplies these three numbers together (length × count × unitWeight) to get the total weight in kilograms.
Feedback & Validation: The result is displayed prominently in a gradient-colored value. If you leave a field empty or enter invalid text (like letters), a friendly error message appears below the button. The tool also includes a subtle fade-in animation for the result, making the feedback feel responsive and polished.
