There are seven measurements in the metric system. When you need to convert one measurment to another one it may be hard to remember all of them off the top of your head so one sentence that is used to remember is,

K= Kilometer
H= Hectometer
D= Decameter
U= Universal, this is where you start when your converting. Underneath this is grams, liters, & meters.
D= Decimeter
C= Centimeter
M= Milimeter
