a centimeter is what fraction of a meter
A centi meter is one hundredth of a meter (1/100) That's the beauty of the decimal system: it's very easy and logical: mili = 1/1000 centi = 1/100 deci = 1/10 By the way, a cubic centimeter (a cube with sides = 1 cm) is exactly one mililiter in volume (1/1000 of a liter).
