For the conversion of standard unit of length the relation between the three units are given below:

1 kilometer = 1000 meters

1 meter = 100 centimeters

Thus,

(i) To convert centimeters (cm) into meters (m), the number of cm is divided by 100.

(ii) To convert kilometer (km) into meters (m), the number of km is multiplied by 1000.

In between centimeter and meter there is a unit of measuring length named decimeter (dm). It is 10 times of a centimeter.
