Apparently, you also need to know the PSI of the wire. Here are the formulas for calculating breaking strength:
Area = ½ Diameter (in inches) Squared x Pi
Minimum breaking strength = Area x PSI
An example for 12½ gauge, 210 (210,000 PSI) wire is:
Area = (.5 x .099") x .0495" x 3.14 = .0077 square inches
Minimum breaking strength = .0077 x 210,000 PSI = 1617 pounds
A 16G 210 has about 614 lbs.
Hope this helps

You also need to consider the hardware you are using to attach the wire to your picture or whatever. It is always better to be safe than sorry and use hardware and wire that will hold twice as much weight as you are hanging. That's what I do because I don't want my stuff falling of the wall and breaking or hurting me. When I was 6 I had a mirror fall off the wall above my dad's bed while I was sleeping in it and if my head hadn't been nestled under his armpit (lol) the glass that went through his shoulder would have stabbed my head.

That will depend on the type of wire. Is it steel or copper? Copper is softer and will have a tendency to stretch.
