Metric Conversion Chart

To convert units:

• identify the prefix of the units you are starting with

• count the number of columns needed to go to the units you need
• move the decimal place over in the same direction by the same number of spaces
• that will be the converted unit.

Ex:
23.3 cg --> ____ dg
To move from "centi-" to "deci-", you need to move one step to the left.
23.3 cg --> 2.33 dg

Factor Label Method (7E only)

Begin by writing the term you need to convert. Choose an appropriate conversion factor and set it up as a fraction beside the term you are converting. Be sure to set up the fraction so that the unwanted terms will cancel out. If more than one conversion is necessary, you can perform them one at a time or all at once.

Ex:

Convert 24 feet into inches
Convert 15 yards into centmeters
