To convert 15 inches to centimeters, we will use the conversion factor of 1 inch = 2.54 centimeters. This means that for every 1 inch, there are 2.54 centimeters.
Step 1: Write down the given value, which is 15 inches.
Step 2: Set up the conversion factor in a fraction form with inches on top and centimeters at the bottom. This will look like: 1 inch / 2.54 centimeters.
Step 3: Multiply the given value (15 inches) by the conversion factor fraction. This will cancel out the inches unit and leave us with centimeters.
15 inches x (1 inch / 2.54 centimeters) = 15 / 2.54 = 5.9 centimeters
Step 4: Round off the decimal value to the desired precision. In this case, we will round off to 1 decimal place, so the final answer is 5.9 centimeters.
Therefore, 15 inches is equal to 5.9 centimeters.
Additional tip: If you want to double check your answer, you can use the reverse conversion by dividing your answer (5.9 cm) by the conversion factor (1 inch / 2.54 cm). You should get the original value of 15 inches.
Note: It is important to keep track of the units and their conversions when performing unit conversions. Canceling out units in fractions ensures that the final value is in the correct unit.
