Which is longer?
A.1 mile or 1 kilometer
B. 1 yard or 1 meter
(. 1 inch Or 1 centimeter

Kilometers (km) are larger than centimeters (cm), so you expect there to be less than one km in a cm. Cm is 10 times smaller than a dm; a dm is 10 times smaller than a m, etc. Since you are going from a smaller unit to a larger unit, divide. ... 1 centimeter (cm) = 0.00001 kilometers (km).

1 inch would be longer then 1 centimeter
