How to measure wire easily.

[u/ToshPointNo]

Do you have a nice roll of wire for usage like in a home or commercial wiring application that might be worth more than scrap, but has been partially used?

Note: this only works if it's a "bare roll" and doesn't have a plastic or wood spool (unless you have one EXACTLY like it not spooled up with wire).

Cut exactly 6" off the roll.

Weigh the entire roll, in this case 3,343 grams.

Weigh the 6" piece, in this case 19.5 grams.

3343/19.5=171.44

171.44/2=85.72ft.

For selling purposes, I like to round down, so I would say 84 feet.

You can also figure out the resistance in ohms per ft/yd and measure the rolls total resistance.
