Millimeters are 1/1000 of a meter, while centimeters are 1/100 of a meter. Say you have a number 678.9 millimeters. If you move the decimal one space to the left, you have 67.89 centimeters, which is 10 times the amount of millimeter ((10)(1/1000) = 1/100). My answer: Move the decimal to the left one space or multiply by ten.
