To convert inches to centimeters, you can use the following formula:
1 inch = 2.54 centimeters
So, to convert 90 inches to centimeters, you would multiply 90 by 2.54:
90 inches * 2.54 cm/inch = 228.6 cm
Therefore, 90 inches is equal to 228.6 centimeters.
Real-life example:
Let’s say you have a TV that measures 90 inches diagonally. To determine the size in centimeters, you would multiply 90 by 2.54 to get 228.6 cm. This would give you a better idea of the actual size of the TV in a unit that is more commonly used in your region.
