1. What is a Diameter Length Calculator for Wire?

Definition: This calculator estimates the length of wire based on its weight, material density, and diameter.

Purpose: It helps electrical engineers, technicians, and DIYers determine how much wire length they have based on weight measurements.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( L \) — Length of wire (meters)
• \( W \) — Weight of wire (kilograms)
• \( D \) — Density of material (kg/m³)
• \( A \) — Cross-sectional area (π × (diameter/2)² in m²)

Explanation: The weight is divided by the product of density and cross-sectional area to determine length.

3. Importance of Wire Length Calculation

Details: Accurate length calculation helps in inventory management, project planning, and cost estimation for wiring projects.

4. Using the Calculator

Tips: Enter the wire weight in kg, material density (default 8960 kg/m³ for copper), and diameter in mm. All values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: What's the default density value?
A: The default is 8960 kg/m³ for copper. Use 2700 for aluminum, 7870 for steel.

Q2: Why is diameter input in mm?
A: Wire diameters are typically measured in millimeters for precision, though the calculation converts to meters.

Q3: How accurate is this calculation?
A: Very accurate for uniform wires, less so for stranded wires due to air gaps between strands.

Q4: Can I use this for non-circular wires?
A: No, this calculator assumes circular cross-section. For other shapes, use the appropriate area formula.

Q5: Does this account for insulation?
A: No, this calculates bare wire length. For insulated wire, use conductor-only weight.
