One centimeter is ${10}^{-} 2$ of a meter.

One millimeter is ${10}^{-} 3$ of a meter.

So, $1$ centimeter is also equal to $10$ millimeters.

If you are changing something from millimeters to centimeters, say $35$ millimeters, this is equivalent to $3.5$ centimeters.

Hope this helps :)

divide by 10

#### Explanation:

In the metric system, each subdivision is 10 times that of the previous one, just like coinage where you need 10 dimes to make a dollar and 10 pennies to make a dime. Metric also uses prefixes to identify the relation of that measurement to the "base" one. They are:

Kilo = $1000$x
Hecto = $100$x
Deca = $10$x

Deci = $\frac{1}{10}$x
Centi = $\frac{1}{100}$x
Milli = $\frac{1}{1000}$x

So in meters, one millimeter is one one thousandth of a meter and a centimeter is one one hundredth of a meter. One centimeter is 10 millimeters and 1 millimeter is one tenth of a centimeter.

1 cm = 10 mm
1 mm = $\frac{1}{10}$ cm = 0.1 cm
