Hello . . .I used to put the metric measurements in the tutorials. To tell you the truth I've gotten lazy because of time. I am sorry to short change you. I did go to the Google page and click the Images tab and type "conversion chart inches millimeters and found many to choose from that you could print out. There is even a picture of an inches ruler compared to a metric ruler. I do apologize for the inconvenience.
