I don't know how to order. I don't want to pay thousands (maybe,
I do?) If I order, say $500.00 worth of gold 20G wire (assuming
it's 14K ) How much would I get - in feet and inches?
Gold (any karat) is usually sold by the pennyweight (dwt)(1 troy
oz equals 20 dwt) or ounce (troy). Sheet goods comes in various
widths, 4 in, 6 in etc. It is sold in strips of that width & as
long as you want up to the maximum length the supplier stocks.
Many times the minimum length sold is about 1/8 in. Minimum
amounts sold are a matter of supplier choice.
Many suppliers will provide you with a chart that lists the
various shapes of wire & sheet they sell. These charts usually
list the length per oz or dwt for the various gauges & shapes of
wire & sheet.
If you have a chart listing one material & want to find the
weight or length of another material there are charts available
to convert from 1 material to another. See Tim McCreight’s, ‘The
Complete Metalsmith’ (page 181 in my copy) for the conversion
factors to convert 18KY, 14KY, 10KY gold, Platinum & Sterling to
several other materials.
Weight & length of 20 ga round Sterling wire.
Conversion factor (cf) for converting sterling to 14KY gold 0.801
1 oz of 20 ga round equals 19 ft.
Find how many ft of 20 ga 14KY gold wire are in 1 oz?
(ft. sterling) X (cf) equals length of 14KY 20 ga round wire in ft.
19 ft X 0.801 equals 15.219 ft of 14KY gold in 1 oz.
To find how much 20 ga 14KY wire is in 1 dwt, multiply ft/oz by 0.05.
15.219 X 0.05 equals 0.76095 ft 20 ga 14KY/dwt
To convert ft/dwt to in/dwt multiply 12 X ft/dwt.
12 x 0.76095 equals 9.1314 inches 14KY gold/ dwt.
