To convert centimeters to inches, you can use the following formula:
inches = centimeters / 2.54
Now, let’s convert 40 centimeters into inches:
inches = 40 / 2.54
inches = 15.75
Therefore, 40 centimeters is equal to 15.75 inches.
Real-life example:
Let’s say you have a piece of fabric that measures 40 centimeters in length. To convert this measurement to inches, you would divide 40 by 2.54 to get 15.75 inches. This would help you determine the length of the fabric in a unit that is more commonly used in the United States.
