If you mean cm, then --

100 cm = 1 m
1000 m = 1 km

Another way of looking at it --

1 centimeter (cm) is about the width of your little finger.

1 meter (m) is about the length of an adult's lower body -- from the floor to the waist.

1 kilometer (km) a little over one-half mile -- or the distance you can walk in 10 or 15 minutes.
