Three ways to calculate wire and cable length

The use of different types of wire and cable will be different. When selecting the type of wire and cable, be sure to confirm it with professional technicians. After purchasing the cable, we need to see if we have purchased so much. This requires us to learn how to measure it. However, many people are not able to measure, so that many manufacturers can not see how many meters, the following there is a cable to tell you about the more commonly used methods to calculate the length of wire and cable 3 methods.

There are 3 ways to calculate the length of the cable and cable of the Thai-Thai brand:

The first method: First cut a bundle of very long wire and cable one meter, and then call the weight of this meter, remember it. Next, the total weight of the wire and cable is also called the weight, and the total weight of the wire and cable is divided by the weight of the one-meter wire and cable, and the total length of the wire and cable is obtained. However, this method would waste the one-meter wire and cable that was cut out, because one meter of wire and cable would not be of any use.

The second method: This is a relatively old-fashioned method. It is to completely unwind the wire and cable, and then use a tape measure to slowly measure the volume. This will not waste the wire and cable. It is also accurate. It is too much trouble and it takes time. It will be more.

The third method: We all know that wire and cable are bundles of a bundle of circles. We can first calculate the length of a circle, and then how many circles there are in total, and then multiply them to get the total length.
