1:48 This ratio means 1 unit of MEASURE = 48 units of the same MEASURE. So if 1 inch = 48 inches, then 1 foot = 48 feet, 1 yard = 48 yards, 1 meter = 48 meters, one kilometer = 48 kilometers and 1 mile = 1 mile. So you can say one inch = 48 inches and multiply 48 X 6 and convert to feet or you can say .5 feet X 48 feet and have the answer already in feet. (or you could multiply 2.4 cm by 6 to convert to centimeters and multiply that by 48 to find answer in cm, or divide that answer by 100 to convert answer to meters).
