What is 27 cm in inch ?
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 27 centimeters to inches, you divide the number of centimeters by the conversion factor:
[
\text{Inches} = \frac{\text{Centimeters}}{2.54}
]
Substituting in the value:
[
\text{Inches} = \frac{27 \text{ cm}}{2.54} \approx 10.6299 \text{ inches}
]
Thus, 27 centimeters is approximately 10.63 inches when rounded to two decimal places.
Explanation of the Conversion Process
Understanding the relationship between centimeters and inches is important in various fields such as science, engineering, and everyday life, especially in contexts where measurements need to be converted between metric and imperial systems. The metric system, which includes centimeters (cm), is widely used globally, whereas the imperial system, which includes inches, is commonly used in the United States.
The basic relationship between centimeters and inches is founded on their definitions: one inch is precisely equal to 2.54 centimeters. This means that when converting from centimeters to inches, we need to account for this ratio. The division by 2.54 serves to translate the longer measurement (in centimeters) into the shorter measurement (in inches).
Using the formula for conversion, it’s essential to ensure that you apply it correctly. For instance, if you have a measurement in centimeters and you wish to express it in inches, you should always divide by 2.54. Similarly, to convert inches back to centimeters, you would multiply the number of inches by 2.54.
In practical terms, knowing how to convert between these two systems allows for accurate measurements when traveling, cooking, or working with international standards. Many tools, such as rulers or measuring tapes, will include both metric and imperial measurements, simplifying the process for users who need to switch between systems frequently.
Overall, understanding these conversions enhances communication and accuracy in various fields and everyday tasks.
