Hope U found your conversion chart crowe. You should be able to find one on the computer. I think what you r wanting is what yarn will replace another n the pattern. Am I right. I've done a lot of knitting n my younger days but had rather crochet than knit cause I do that faster. I have had conversion tables n the past but have no idea what I did with them. My mom was a big knitter & I've probably got around 100 prs of all kinds of needles. *4U

I don't know what kind of conversion chart you are looking for but here a link that might be what you want
