Fillet Gauge Inch

In Maker Faire Bay Area 2016 I participated with my Stainless Steel Fillet Gauge and a lot of the suggestions I got were about an inch version of it. Living in Europe, I don't use inches, and I am not familiar with it. I found a inch to mm table and I tried to put the ones that made sense to me but I am not sure if I put the correct fractions. If you can help me out I would be very pleased. The table I used: https://mdmetric.com/tech/cvtchtfdm.htm
