Well, I think most of us understand what a 10/10 or 10/14 or 14/14 is but

What is a 9/45 or 10.5/48 or even 12.5/63 ?

Having seen a 6/45 and 8/45, there is not a substantial difference. I suppose I should do the quarter test but at first glance it looks an awful lot like a 9/9 or so...well, perhaps 8/8 . I'll do that quarter test as soon as I can find someone here in the building with a quarter. LOL
(Yes, all of the designations are from India.)

I did a quarter test . Can't seem to get the pic loaded here but it ends up counting pretty coarse at about 6 1/2 x 7 - very close to 7/7 but not quite there. and this is a "6/45"

yes this measurement they use for square knots certainly is one of the easier to translate into a quantifiable knot count. There are ways to translate 9/45 and all the others, but it's somewhat of a cheap translation as the true count usually gets muddled quite a bit. Also, a quarter I believe is just a fraction under one inch diameter, although I could be mistaken. Here is the translation as taken from the main site: "As seen in the chart up top, there are two+ units of measure for Indian rugs. One is the traditional knot grid, and the other is square knots. India 1 as marked below refers to the traditional knot grid, of which the conversion is somewhat inaccurate, although more often than not within 10% of true KPSI. For the formula of India 1 KPSI conversion, multiply the numerator and denominator, then divide by 4. " This means that a 14/70 = somewhere around 245 KPSI which is a rough estimate.
