1. What is a Steel Coil Size Calculator?

Definition: This calculator estimates the length of a steel coil based on its weight, width, thickness, and material density.

Purpose: It helps metalworking professionals and engineers determine the length of steel coils for manufacturing and inventory purposes.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( L \) — Length of steel coil (meters)
• \( W \) — Weight of the coil (kilograms)
• \( W_d \) — Width of the coil (meters)
• \( T \) — Thickness of the steel (meters)
• \( D \) — Density of steel (kg/m³, typically 7850)

Explanation: The weight is divided by the product of width, thickness and density to calculate the unrolled length.

3. Importance of Steel Coil Length Calculation

Details: Accurate length calculation ensures proper material planning, production efficiency, and cost control in metal fabrication.

4. Using the Calculator

Tips: Enter the weight in kg, width in meters, thickness in meters, and density (default 7850 kg/m³ for steel). All values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: What's the standard density for steel?
A: The density of carbon steel is typically 7850 kg/m³, but this may vary slightly for different alloys.

Q2: How precise should thickness measurements be?
A: Steel thickness is often measured in millimeters or fractions of millimeters, so use precise measurements (0.001m = 1mm).

Q3: Can this calculator be used for other metals?
A: Yes, simply adjust the density value (e.g., 2700 kg/m³ for aluminum).

Q4: Why is width important in the calculation?
A: Width determines the cross-sectional area of the unrolled coil along with thickness.

Q5: How does coil tightness affect the result?
A: This calculation assumes perfect unrolling. In practice, tight coils may have slightly different actual lengths.
