To calculate the weight of a copper wire, you'll need to know the dimensions of the wire (typically its diameter or cross-sectional area) and its length. Copper wire weight is determined by its volume and density. Here's the formula:
Weight = Volume × Density
Calculate the volume of the wire:
Measure the length (L) of the wire in the appropriate units (e.g., meters, feet, inches).
Look up the density of copper. The density of copper can vary slightly, but a common value is around 8,960 kg/m³ or 8.96 g/cm³.
Plug in the values into the formula:
Finally, calculate the weight using the formula: Weight = Volume × Density
Make sure to use consistent units for all measurements. If you're using different units, you might need to convert them to the same unit before doing the calculations.
Here's a summary of the formulas:
If you have the diameter (D) and length (L):
Cross-sectional Area (A) = π(D/2)^2 Volume = A × L Weight = Volume × Density
If you have the cross-sectional area (A) and length (L):
Volume = A × L Weight = Volume × Density
Remember that this calculation assumes a uniform wire with a consistent diameter or cross-sectional area along its length. If the wire isn't uniform, you'll need to break it down into sections with different diameters or areas and calculate their weights separately.
