To convert inches to centimeters, you can use the following formula:
1 inch = 2.54 centimeters
So to convert 20 inches to centimeters, you would multiply 20 by 2.54:
20 inches * 2.54 cm/inch = 50.8 cm
Therefore, 20 inches is equal to 50.8 centimeters.
Real-life example:
Let’s say you have a TV that measures 40 inches in diagonal length. To find out how long it is in centimeters, you would use the conversion factor:
40 inches * 2.54 cm/inch = 101.6 cm
So, a TV that is 40 inches long is equivalent to 101.6 centimeters.
