In the United States, most people measure their height in feet and inches. However, the majority of the rest of the world uses centimeters. Therefore, to compare your height to heights listed in other countries, you need to be able to convert it to centimeters from feet and inches. For example, you might go to an amusement park in a foreign country and need to know if you can go on a ride based on your height, but the height requirement is in centimeters.

Multiply the height in feet by 30.48 to convert to centimeters. For example, if you are 5 feet 3 inches tall, multiply 5 by 30.48 to get 152.4 centimeters.

Multiply the height in inches by 2.54. In this example, multiply 3 by 2.54 to get 7.62 centimeters.

Add the Step 1 result to the Step 2 result to calculate the height in centimeters. Finishing the example, add 152.4 centimeters to 7.62 centimeters to get a total of 160.02 centimeters.
