The physical properties of copper, particularly its high conductivity and malleability, make it an essential material in various fields. Understanding the weight of a copper wire, determined by its volume and density, is crucial in these applications. This article introduces a handy tool: the Copper Wire Weight Calculator.


A Copper Wire Weight Calculator is a digital tool designed to calculate the weight of a copper wire based on its length and diameter. By leveraging fundamental physics and mathematical principles, it provides quick and accurate results, assisting in numerous technical and industrial applications.

Detailed Explanation of the Calculator’s Working

The calculator operates on a straightforward principle. It takes the diameter and length of the wire as inputs, then computes the volume using the formula for the volume of a cylinder. Multiplying this volume by the density of copper, the weight of the wire is obtained.

Formula with Variables Description

The formula the calculator employs is as follows:

Weight = Volume x Density

The volume (in cubic meters) of a cylindrical wire is calculated by:

Volume = (π/4) x (Diameter^2) x (Length)


π is the mathematical constant pi (approximately 3.14159)
Diameter is the diameter of the wire (in meters)
Length is the length of the wire (in meters)

By considering the density of copper (approximately 8.96 g/cm^3), we can obtain the wire’s weight in kilograms.


For instance, consider a copper wire with a diameter of 0.01 m and a length of 100 m. The calculator computes the weight as approximately 7.07 kg.
