📏 Formula Behind the Copper Wire Weight Calculator
The formula used by the Copper Wire Weight Calculator is based on the volume of the wire and its density. Here’s a step-by-step breakdown:
Formula:
Copper Wire Weight (lbs) = (π × (Diameter/2)² / 144) × Length × Density
Where:
- π (Pi) is approximately 3.1416
- Diameter/2 is the radius of the wire
- Diameter is the wire’s diameter in inches
- 144 is a conversion factor to adjust the units to square feet (since diameter is given in inches)
- Length is the wire’s length in feet
- Density is the copper wire’s density in lbs/ft³
Explanation:
- The first part of the formula, π × (Diameter/2)², calculates the cross-sectional area of the wire (circular cross-section).
- Dividing by 144 converts the area to square feet (since 1 square foot = 144 square inches).
- Then, multiplying the area by the length of the wire gives the volume of the wire in cubic feet.
- Finally, multiplying the volume by the density of copper gives the weight in pounds.
✅ Example Calculation
Let’s walk through an example calculation for a copper wire:
- Diameter = 0.25 inches
- Length = 100 feet
- Density = 559 lbs/ft³ (standard for pure copper)
Step-by-Step Calculation:
- Find the radius:
Diameter / 2 = 0.25 / 2 = 0.125 inches - Square the radius:
0.125² = 0.015625 square inches - Calculate the cross-sectional area:
Area = π × 0.015625 ≈ 0.049087 square inches - Convert to square feet:
0.049087 ÷ 144 ≈ 0.000340 square feet - Find the volume:
Volume = 0.000340 square feet × 100 feet = 0.0340 cubic feet - Calculate the weight:
Weight = 0.0340 cubic feet × 559 lbs/ft³ ≈ 19.0 lbs
Result: The weight of the copper wire is approximately 19.0 lbs.
📎 Additional Insights About Copper Wire Weight
