I couldn't find any kind of conversion chart for this thread online. You may want to contact the manufacturer - it looks like Loops & Threads is owned by Michael's. Send them an email and see if they have a conversion chart available. Most of the thread companies are really good about providing that kind of information for their customers. Good Luck!!
