How to convert 38 cm to inches?
The Correct answer and Explanation is:
To convert centimeters to inches, you can use the conversion factor that 1 inch is equal to 2.54 centimeters. Therefore, to convert 38 centimeters to inches, you can use the following formula:
[
\text{Inches} = \frac{\text{Centimeters}}{2.54}
]
Substituting the value:
[
\text{Inches} = \frac{38 \text{ cm}}{2.54} \approx 14.96 \text{ inches}
]
Thus, 38 cm is approximately 14.96 inches.
Explanation
Understanding how to convert measurements from centimeters to inches is crucial in various fields, including science, engineering, and daily life. The metric system (centimeters) and the imperial system (inches) are commonly used measurement systems worldwide. While the metric system is predominant in most countries, the imperial system remains widely used in the United States.
The conversion factor between these two systems is based on a defined relationship: 1 inch is equal to 2.54 centimeters. This factor means that there are approximately 2.54 centimeters in every inch. Therefore, when converting centimeters to inches, you divide the number of centimeters by 2.54.
In practical applications, such as in construction, tailoring, or healthcare, accurate conversions are essential. For example, a tailor might need to convert a measurement given in centimeters into inches to ensure the right fit for clothing. Similarly, a healthcare professional may need to convert a patient’s height from centimeters to inches for documentation purposes.
In our calculation, we started with the measurement of 38 cm and applied the conversion factor. By dividing 38 by 2.54, we obtained the result in inches. It is important to remember to round the result to an appropriate number of decimal places based on the context of the measurement. In this case, we rounded to two decimal places, resulting in approximately 14.96 inches. This level of precision is generally sufficient for most practical purposes.
