How to convert metric units:
Each step on the number line is one decimal place. To convert you move the decimal place the same number of jumps on the metric line. In class we used this version:
Each step represents a decimal place. Star where you are and star where you are going. However many hops to get where you are going is how many decimal places you move the decimal. You move the decimal in the same direction you went (left or right).
You should know what the prefixes mean (like centi means 1/100, like there are 100 cents in a dollar there are 100 centimeters in a meter). If you don't know these you should definitely check out the metric prefixes page.
