Changing Metric Units

To go from one unit of measurement to another unit simply:

move the decimal to the left or the right the necessary number of spaces

Example:

convert 125 cm to m

1. write the metric units

2. put your finger on the starting unit

3. slide your finger along the line to the desired unit, counting how many spaces you moved

4. move the decimal the number of spaces you counted in the direction you slid your finger (left/right)

km hm dam m dm cm mm

125 cm = 1.25 m

The Magic of the Metric System

1 cm3 = 1 mL = 1 g

When using the metric system one can easily

go from units measuring mass or volume.
