How Much Does Copper Wire Weight per Foot?

Copper wire is a versatile and commonly used material in various electrical applications. Whether you are an electrician, a DIY enthusiast, or simply curious about the weight of copper wire per foot, this article will provide you with all the necessary information.

Copper Wire Weight per Foot

The weight of copper wire per foot can vary depending on its gauge or thickness. The American Wire Gauge (AWG) system is commonly used to measure the diameter of copper wire. The higher the AWG number, the thinner the wire.

To give you a general idea, here are the typical weights for copper wire per foot based on different AWG sizes:

– 10 AWG: 0.101 lb/ft
– 12 AWG: 0.0808 lb/ft
– 14 AWG: 0.0641 lb/ft
– 16 AWG: 0.0509 lb/ft
– 18 AWG: 0.0401 lb/ft
– 20 AWG: 0.0318 lb/ft
– 22 AWG: 0.0252 lb/ft
– 24 AWG: 0.0199 lb/ft

It is important to note that these weights are approximate and may vary slightly depending on the specific manufacturing process or copper alloy used.

Factors Affecting Copper Wire Weight

Apart from the gauge, there are a few other factors that can influence the weight of copper wire per foot:

1. Copper Alloy: Copper wire is often alloyed with other metals to enhance its properties. Different alloys can have slightly different densities, which can affect the weight per foot.

2. Insulation: Copper wire is commonly insulated with a thin layer of non-conductive material such as PVC or rubber. The weight of the insulation adds to the overall weight per foot.

3. Stranding: Copper wire can be solid or stranded, where multiple smaller strands are twisted together to form a single wire. Stranded wire tends to be slightly heavier due to the additional material required for the stranding process.


Q: Why is the weight of copper wire per foot important?
A: Knowing the weight of copper wire per foot is essential for various applications, such as determining the overall weight of a spool or calculating the weight of copper wire needed for a particular project.

Q: Can the weight of copper wire affect its electrical conductivity?
A: The weight of copper wire does not directly affect its electrical conductivity. However, a thicker wire with a larger cross-sectional area can carry more current with less resistance.

Q: Is the weight of copper wire per foot the same for all suppliers?
A: The weight of copper wire per foot can vary slightly between different suppliers due to variations in manufacturing processes and copper alloys used. It is always best to check with the specific supplier for accurate weight information.

Q: How can I calculate the weight of copper wire for a specific length?
A: To calculate the weight of copper wire for a specific length, multiply the weight per foot by the desired length in feet. For example, if the weight per foot is 0.0808 lb and you need 100 feet, the total weight would be 0.0808 lb/ft x 100 ft = 8.08 lb.

In conclusion, the weight of copper wire per foot varies depending on the gauge or thickness. Understanding the weight is crucial for various applications and projects involving copper wire.
