* The units of measure can be changed by choosing a unit from the combo box (meters, centimeters, inches, feet, yards, or custom units) on the Customize toolbar. If you chose "custom units", the current distance between the two laptops will be used as a metric. For example, you could measure the height of a student, Pedro, and then select that distance to define a new unit of measure, the "Pedro" (See [http://en.wikipedia.org/wiki/Smoot]).
