centimeters has a prefix centi- which is similar to our cents and dollars. A cent is 1% of a dollar. $1 = 100 pennies or cents. a centimeter is 1% of a meter, numerically, ignoring units. m=.01c =c/100 there's one hundred centimeters in 1 meter. Just as there're 100 pennies in a dollar P=100D

c = 100m

c = 100(7) = 700 cm.
