Wire Gauge Conversion Chart

£0.00

Wire Gauge Conversion Chart, digital PDF file for downloading and printing. For silversmiths to work out approximate width of wire or sheet to order and cut. NOT a size conversion chart! It will be available to download once your order is marked as “shipped” by us, which is done manually – so it won’t be available straight away.

Description



Wire Gauge Conversion Chart for working out the width of metal sheet or wire. Here’s the GoogleDoc version if you’d like to keep the resource there 🙂 Also see the Free Ring Cutting Size Chart for working out the length and width of metal sheet or wire. Shown in UK and US or metric and imperial measurements, Please “purchase” this separately to any products that need shipping so we can mark it completed straight away!

Soldering a Teardrop Ring Video

 

Here is the full blog for the Soldering a Teardrop Ring tutorial with all the supplies I used in the video.

We don’t recommend using tape to measure ring sizes, we recommend you send your customer a plastic multi ring sizer with their kit. Whatever size your client is, we recommend cutting the length in mm from the righthand column. If you like to pierce through the ring several times when bringing the ends together to form the shank, you might want to add an additional mm. If you’re very accurate at piercing and you don’t cut through, you might be able to take off a mm. Please do not use this chart for gold until you have practice with silver rings, to avoid costly mistakes. This is the chart Nikki has been using for four years, creating thousands and thousands of keepsake and blank rings, now available to you free of charge!

How To Use the Free Wire Gauge Conversion Chart

After you’ve established your customer’s ring size with a multi ring sizer then use a set of digital calipers to measure the length of wire or sheet you want to cut using the length on the column on the right hand side (+4mm), marking it with a Sharpie. Full tutorial coming soon. Watch Nikki do this on the Keepsaker Supplies TikTok page make a ring from start to finish with twisted wire!


Ring Sizing Chart – UK and US Sizes

Ring sizing chart UK and US sizes, also EU sizes (which is mm circumference), use at your own discretion. We aren’t liable for any loss of income or mistakes in cutting precious metal for use of this chart, it is meant solely as a guide.

And if you’re wondering where I get all my graphics from, I do it myself! I use a combination of copyright-free images and design elements from Creative Market. They do a set of six freebies every week, here’s this week’s. Definitely worth a look:

Gauge is a measurement of wire diameter, and it’s important to note that there isn’t one universal gauge system. The two most common are American Wire Gauge (AWG) and Standard Wire Gauge (SWG, primarily used in the UK). There are also different gauge systems for sheet metal, jewellery, and even body piercing.

Generally, the smaller the gauge number, the thicker the wire or material.

Here’s a general mm to gauge conversion chart for common wire gauges. Keep in mind that exact conversions can vary slightly between different standards and manufacturers.

Important Considerations:

  • AWG vs. SWG: If you are working with electrical wiring, especially in North America, AWG (American Wire Gauge) is the standard. If you are in the UK, SWG (Standard Wire Gauge) might be more relevant. The values for the same gauge number differ between these two systems.
  • Application-Specific Gauges: As mentioned, there are different gauge systems for various materials (e.g., sheet metal, body jewelry). Always ensure you are using the correct conversion chart for your specific application.
  • Exactness: Gauge sizes are not always exact conversions to precise millimeter measurements due to the nature of their historical development. The charts provide very close approximations.
  • Stranded Wire: The chart above typically refers to the diameter of a solid conductor. For stranded wire, the gauge refers to the equivalent cross-sectional area of the combined strands.
