Because I have worked all my life as a woodworker I am confused with inches and mm. I would like to know if there is a way how to turn the inches to mm or vice versa.


My favorite length conversion calculator is free, follow this link: Conversion Calculator

    unless I am missing something, I did not see a conversion for mm, the thing most of us need the most. the smallest I saw was cm on the metric side.

      Helen, just scroll down the right hand chart – mm is second from the bottom.

    Another way,

    If you use the US Quarter ( $.25 ) as a reference it might also help.
    Our quarter is about 1 inch and also about 25 mm.
    Or to convert inches to mm just multiply by 25.4 and to convert mm to inches just multiply by .03937

    To change inches to millimeters: multiply inches by 25.4
    Example. 2 inches X 25.4 = 50.8 millimeters

    To change millimeters to inches: divide millimeters by 25.4
    Example. 50.8 millimeters divided by 25.4 = 2 inches

    There are exactly 25.4 millimeters in 1 inch.

    Hope this helps.

    Here is my favorite conversion calculator online:
    http://www.worldwidemetric.com and conversion calculators can be purchased to take with you to shows, etc. I had one that I used for years until it simply died of old age. I can’t tell you how musch use I got out of it and carried it in my purse at all times. (It helped me to half and double recipes ingredients, too.)

    I never learned metric conversion. Found it very confusing, especially since it does not translate directly into inches and feet. I finally bought a ruler that had inches on one side and metric measurements on the other. When I need millimeters I ignore the inch side and vice versa. It’s much easier than trying to convert. Such rulers are easy to find in business supply stores. Also in dollar stores, etc. Just check each edge of the ruler to make sure it has both types.
