When I lived in Taiwan, we went to a special fabric area near old downtown Taipei to buy fabric. The vendors gave us a choice of yards, meters, or some Chinese unit of measure-all for the same price per unit. I used to laugh to myself when other Americans insisted that they would only buy yards, effectively cheating themselves out of several extra inches of fabric per unit purchased. Inches or centimeters- it doesn't matter if you have a good ruler and know how to use it!
