To convert centimeters to inches, you can use the following formula:
inches = centimeters / 2.54
Now, let’s convert 138 cm to inches:
inches = 138 / 2.54
inches = 54.33
Therefore, 138 cm is equal to 54.33 inches.
Real-life example:
Let’s say you have a piece of fabric that measures 138 cm in length. To convert this measurement to inches, you would divide 138 by 2.54 to get 54.33 inches. This conversion would be useful if you were trying to determine how much fabric you would need for a project that requires measurements in inches.
