How do you convert m to mm?

mm means millimeters. m means meters. use this: KHDBDCM (i remember it "Kevin Helps Dennis Bake Delicious Corn Muffins") It really stands for Kilo Hecto Deca Base (which means meter liter gram) Deci Centi Milli. Ok. So now let's say that you have 15 millimeters and you want to convert it to meters. You would take 15 and put a decimal point at the end of it. Then look at your chart. Base (meters) is 3 places behind milli, so you move the decimal place back three places. That gives you your answer of 15 mm=0.015 meters. I hope that helps! :)
