First, we need to understand the unit of inches. Inches is a unit of measurement commonly used for lengths in the United States and some other countries. It is represented by the symbol “in” or double prime (“).

To convert 54 inches into a different unit of length, we will use the conversion factor of 1 inch = 2.54 centimeters. This conversion factor is derived from the conversion between the two most commonly used units for length – inches and centimeters.

Step 1: Write down the conversion factor.

1 inch = 2.54 centimeters

This means that 1 inch is equal to 2.54 centimeters.

Step 2: Set up the conversion equation.

We will use the conversion factor to set up a conversion equation, which will help us to convert the unit of 54 inches into a different unit.

54 inches x 2.54 centimeters / 1 inch = ? centimeters

Note that the units of inches will cancel out in the equation, leaving us with the unit of centimeters.

Step 3: Simplify the equation.

Next, we will simplify the equation to solve for ? centimeters.

54 x 2.54 = ?

After simplifying, we get:

? = 137.16

Step 4: Interpret the result.

The result we got is the value of 54 inches in centimeters. Therefore, 54 inches is equal to 137.16 centimeters.

Step 5: Write the final answer.

To convert 54 inches to centimeters, we use the conversion factor of 1 inch = 2.54 centimeters. After solving the equation, we get the value of 137.16 centimeters. Hence, the final answer is:

54 inches = 137.16 centimeters

In summary, to convert a unit of length (in this case, 54 inches) into a different unit, we use a conversion factor and set up a conversion equation. We then simplify the equation and interpret the result to obtain the final answer. I hope this helped you in understanding the process of converting the unit of length.
