weight to length with copper wire

I have a problem . My conversion consist's of varying guages of copper wire(labelled in KG's not length) to be converted to meters. For example I have a chart that states 22awg(7Bit) copper wire is as follows; Kilogram/kilometer is 3.17 as 50 kilograms = 15,773 Meters, or 10awg(104bit) copper wire is 47.49(kilogram/kilometer) where 50kg = 1,053Meters. I was wandering If you may be able to help apply this info to create a base formula or equation to apply to any quage of wire. As I said I do have a list of KG/KM. Thanx in advance Dennis

Re: weight to length with copper wire

Not exactly sure what you are after, but it would be different for each guage of wire, but you have the density of each so it would be easy, just different.

kilograms of wire * kg/km = kilometers of wire

Where kg/km is your wire density, which you list as different for each guage.

Re: weight to length with copper wire

Rob's post applies to any gauge of wire you know the density for. it won't tell you the density of the wire, however. you will have to find that out on your own, either from your own testings, or from the manufacturer. you can easily weigh one meter of wire, multiply that by 1 000, and you'll get, roughly, the weight of 1 km of wire.
example: weigh 1 meter of wire X.
it weighs 20 grams, multiply that by 1 000, you get 20 000
so 1 kilometer of wire X weighs 20 000 grams, or 20 kilograms

Re: weight to length with copper wire

For general electrical wiring conductor (plain soft copper) the following formulae has worked for me for past 30 years;

(indiv strand size)² x 6.98 x (No. of ends) = kg/km

There is 100mm² in 1cm², and there is 100cm in 1m

copper has a density of about 8.92g/cc, so 2.4cm² x 100cm x 8.92 = 2141g, or 2.14kg per meter.

Do you have a reference for this? Never heard of it.

From http://en.wikipedia.org/wiki/Wire

"Number of strands

The more individual wire strands in a wire bundle, the more flexible, kink-resistant, break-resistant, and stronger the wire is. But more strands cost more.

The lowest number of strands is 7: one in the middle, 6 surrounding it.
The next level up is 19, which is another layer of 12 strands on top of the 7. After that the number varies, but 37 and 49 are common, then in the 70 to 100 range (the number is no longer exact). Even larger numbers than that are typically found only in very large wires.

For application where the wire moves, 19 is the lowest that should be used (7 should only be used in applications where the wire is placed and then doesn't move), and 49 is much better. For applications with constant repeated movement, such as assembly robots, and headphone wires, 70 to 100 is mandatory.

For applications that need even more flexibility (welding is the usual example, but also any need to move wire in tight areas), even more strands are used. One example is a 2/0 wire made from 5,292 strands of #36 gauge wire. The strands are organized by first creating a bundle of 7 strands. Then 7 of these bundles are put together into super bundles. Finally 108 super bundles are used to make the final cable. Each group of wires is wound in a helix so that when the wire is flexed, the part of a bundle that is stretched moves around the helix to a part that is compressed to allow the wire to have less stress."

Re: weight to length with copper wire

The Std.Formula for the weight calculation of cable conductor is
(Number of core x dia of conductor x 0.0089).

you will get the total cupper in one meter and multiply that with 1000 .you will get the 1km cable conductor wieght.
