A unit conversion expresses the same property as a different unit of measurement. You can always multiply a quantity by 1 or conversion factors, as a consequence the quantity remains the same. The process is called the chain-link method. Practice it by doing the following problems: Problems: 1. Convert 12 inches to cm (1 inch = 2.54 cm) 12 in 2.54 cm x 1 in 2. Convert 70 mph to m/s. (1 mile=5280 ft, 1 m = 3.28 ft, 1 hour = 3600 s) 3. Convert 16 oz to Liters. (1 oz = 29.57 cm, 1 L = 1000 cm) 4. Convert 300 square feet to square meters
