6.7 feet on a tape measure corresponds to 6 feet and 8.4 inches, since there are 12 inches in a foot. To find the inches, you multiply the decimal (.7) by 12, which equals 8.4. Therefore, when reading a tape measure, you would locate the 6-foot mark and then move to just past the 8-inch mark to indicate 6.7 feet.
