Weight and Price Calculation Method of Scrap Copper Wire

The weight of scrap copper wire can be calculated according to the length and diameter. 

The specific calculation method is as follows:

1. Calculate the length

First you need to measure the length of the scrap copper wire. Generally speaking, scrap copper wires are coiled together, so they need to be unrolled.

2. Measure the diameter

Then you need to measure the diameter of the scrap copper wire. This can be measured with calipers or other tools.

3. Calculate the cross-sectional area

According to the diameter of scrap copper wire, its cross-sectional area can be calculated. The specific calculation formula is: cross-sectional area = π × (diameter/2)^2

4. Calculate the weight

Finally, according to the length, cross-sectional area and density of the scrap copper wire (approximately 8.9 g/cm³), the weight of the scrap copper wire can be calculated. The specific calculation formula is: weight = length × cross-sectional area × density

The price of scrap copper wire mainly depends on its purity and market price. The specific calculation method is as follows:

1. Estimated purity

The purity of scrap copper wire is usually impure, so it needs to be estimated based on its appearance and source. Generally speaking, the purity of scrap copper wire varies from 50% to 99%.

2. Find market prices

After determining the purity of scrap copper wire, you can find the market price. Inquiries can be made through the Internet and mobile phone applications. It is recommended to compare multiple channels to avoid being fooled.

3. Calculate the price

Finally, the total price can be obtained by multiplying the weight of scrap copper wire and the market price. The specific calculation formula is: price = weight × market price

The calculation method of the weight and price of scrap copper wire is relatively simple, and it only needs to be calculated according to factors such as length, diameter, density, purity and market price. However, since the price of scrap copper wire is greatly affected by the market, the price calculation method provided in this article cannot be guaranteed to be accurate. Readers are requested to calculate according to the actual situation.
