Measurement conversion is a useful skill to know if you travel from the United States to a different country. The United States is one of the only countries in the world that doesn't use the metric system, so measurements can cause confusion if you aren't prepared. Two of the more common measurements that need to be converted are inches to centimeters and pounds to kilograms. As long as you have a calculator or pen and paper, these conversions can be made in a matter of seconds.
Divide the number of pounds by 2.20462262 to convert it to kilograms. For example, if an object weighs 5 pounds, divide it by 2.20462262 to get 2.6796. If you need a general number, rather than an exact number, you can divide the number of pounds by 2.2.
Multiply the number of inches by 2.54 to convert it to centimeters. For example, if an object is 12 inches long, multiply it by 2.54 to get 30.48 centimeters.
