Five feet and 4 inches is equivalent to 162.56 centimeters. To determine this conversion, first change 5 feet to 60 inches. Next add the 4 inches to 60 inches to equal 64 inches; then multiply 64 inches by a conversion factor of 2.54 centimeters per inch to reach 162.56 centimeters.
This process is called unit conversion. Any unit can be converted into any other unit as long as it is measuring the same property. For example, it works to convert feet and inches to centimeters, because they both measure length. It is not practical to convert inches to pounds, because inches measure length while pounds measure weight.
