Wire Weight Results
Formula used: Weight = Density × Cross-sectional Area × Length
Cross-sectional area: 3.3103 mm²
Material density: 8960 kg/m³
Example Calculation
AWG 12 Copper Wire (1 foot)
Wire type: AWG 12 round copper wire
Diameter: 2.053 mm (0.081 inches)
Length: 1 foot (0.3048 m)
Material: Pure copper (8,960 kg/m³)
Calculation Steps
1. Cross-sectional area = π × (D/2)² = π × (2.053/2)² = 3.31 mm²
2. Area in m² = 3.31 × 10⁻⁶ m²
3. Length = 0.3048 m
4. Weight = 8,960 × 3.31×10⁻⁶ × 0.3048
5. Weight = 0.009 kg = 9.0 g = 0.020 lb

Quick Tips
AWG 12 and 14 are common for household wiring
Telephone wire is typically AWG 22, 24, or 26
Higher AWG numbers mean smaller diameter wire
Pure copper has excellent electrical conductivity
Copper is heavier than aluminum but lighter than silver
Understanding Copper Wire Weight Calculations
Why Calculate Wire Weight?
Calculating copper wire weight is essential for electrical engineers, contractors, and buyers who need to: estimate material costs, plan installations, calculate shipping weights, and ensure structural load capacity.
Copper vs Other Materials
- •Copper: Excellent conductivity, durable, but heavy
- •Aluminum: Lighter and cheaper but lower conductivity
- •Silver: Best conductivity but very expensive
Calculation Formulas
Basic Formula
Weight = Density × Area × Length
Round Wire
W = ρ × π × (D/2)² × L
Square Wire
W = ρ × A² × L
Rectangular Wire
W = ρ × A × B × L
W: Weight
ρ: Material density
D: Diameter
A, B: Side dimensions
L: Length
