What thread are you using and what do you want to convert from? You can google thread conversion charts on the web and it will give you maderia, isocord, robison anton etc.... Also Embroidery Library had one too you cna put in the numbers that you have and pick the company you want to convert to and it does it for you. Hope this helps. Suzanne
