Metal Calculators

Wire Calculation

The product pages for the wire list the weight per metre for the popular sizes of wire.

If you multiply the length you want (in metres) by this number, you will get the approximate weight for the metal you are ordering

 

Example:

3mm Sterling Round wire lists 73.5 g per metre.

If you want 400mm, that is 0.4m

so 0.4 x 73.5 = 29.4g (approximately)

 

Please see the top of the page for Sterling and Fine silver wires for the minimum cut length.

 

Other Calculators

To calculate the length of Wire required for a Bangle: Add the thickness of the wire you are using to the Inside Diameter, then multiply by Pi (3.1416)

Example:

63mm I.D from 3.0mm Round Wire
63 (the I.D) + 3 (the wire thickness)
66.0 x 3.1416 = 207.35mm therefore length required is approximately 210mm

Calculator:

Inside Diameter (mm) Wire Thicknes (mm) Pi Length of Wire Required (mm)

To convert from one alloy to another divide weight by the known alloy density and then multiply by wanted alloy density.

Example:

A ring weighing 3.0 grams in Stg wanted in 18ct Yellow.
3 / 10.4 x 15.5 = 4.5 grams

Calculator:

Plate Area - Weight

LENGTH(mm) x WEIGHT(mm) x THICKNESS(mm) x ALLOYS DENSITY / 1000

Example:

Stg Silver Plate

100mm x 120mm x0.8mm
100 x 120 x 0.8x 10.4 / 1000 = 99.84 grams
