Shoe Size to Inches

Probably everyone knew this but me, but just in case....

Here's a conversion chart of shoe sizes to the equivalent in inches: Conversion Chart. As we knit socks for relatives in far-away places, this tool might be helpful. Interestingly, sizing doesn't seem to be consistent. Sometimes the jump between sizes is 3/16"; sometimes it's more. I guess inconsistent sizing isn't really news, now is it?
