 * Possible values:
 *      - English   displays as "42 feet"
 *      - Metric    displays as "42 meters"
 *              * Of course the metric and english values would be different
 *                I'm just too lazy to do the conversion for this example.
 *                Although it's ironic I made such a long comment about it.
