Metric To Metric Conversion Step One: Line up the metric units from largest to smallest:    km hm dam m dm cm mm   kl hl dal l dl cl ml kg hg dag g dg cg mg Step Two: Count the number of steps from the unit you have to the unit you want. Step Three: Move the decimal point the direction you moved to get from one unit to the other that many steps.

4.5 L = ml Step One: Line up the metric units from largest to smallest:   kl hl dal l dl cl ml Step Two: Count the number of steps from the unit you have to the unit you want in your answer. To get from liters to milliliters on the chart, it takes three steps to the right. Step Three: Move the decimal point the same direction you moved. So the decimal point must be moved three steps to the right as well. 4.5 L = 4,500 ml
