Linear Foot Formula:
From: | To: |
Definition: This calculator estimates the linear footage of steel coil based on weight, dimensions, and material density.
Purpose: It helps metal fabricators, manufacturers, and distributors determine how much linear footage is contained in a steel coil.
The calculator uses the formula:
Where:
Explanation: The formula calculates how many linear feet of material are contained in a coil based on its total weight and cross-sectional area.
Details: Accurate linear footage calculations are essential for inventory management, production planning, material ordering, and pricing in the steel industry.
Tips: Enter the coil weight in pounds, strip width in inches, material thickness in inches, and density (default 0.284 lb/in³ for steel). All values must be > 0.
Q1: Why is density important in this calculation?
A: Density accounts for the material type (steel, aluminum, etc.) as different materials with the same dimensions will have different weights.
Q2: What's the standard density for steel?
A: Carbon steel typically has a density of 0.284 lb/in³, but this may vary slightly by alloy composition.
Q3: Can I use this for other metals besides steel?
A: Yes, just adjust the density value (e.g., 0.098 lb/in³ for aluminum, 0.323 lb/in³ for stainless steel).
Q4: How accurate is this calculation?
A: It provides a theoretical estimate. Actual length may vary slightly due to coil tension, edge trim, or coating thickness.
Q5: What if my coil has multiple plies?
A: The calculation works the same way as it's based on total weight and cross-sectional area per linear foot.
