If one inch is equivalent to 2.54 CM then how many in these are there there in 20.8 cm
The correct answer and explanation is:
To convert 20.8 cm to inches, we use the given conversion factor: 1 inch = 2.54 cm.
The formula for converting centimeters to inches is: Inches=Centimeters2.54\text{Inches} = \frac{\text{Centimeters}}{2.54}
So, to find how many inches are in 20.8 cm: Inches=20.82.54=8.19 inches\text{Inches} = \frac{20.8}{2.54} = 8.19 \text{ inches}
Thus, 20.8 cm is approximately equal to 8.19 inches.
Explanation:
When working with unit conversions, it’s essential to know the correct relationship between the units you are converting. In this case, we are converting from centimeters (cm) to inches. The relationship between these two units is that 1 inch is equal to 2.54 cm. This means that for every inch, the length in centimeters increases by 2.54.
By using the formula and dividing the length in centimeters by 2.54, you obtain the equivalent length in inches. This division method ensures that the units of centimeters cancel out, leaving you with the correct number of inches.
Unit conversions are useful in various contexts such as measurements in different systems or countries that use different standards. In science, engineering, and everyday life, these conversions help make measurements more consistent across different systems. Whether you’re working with imperial units or metric units, knowing how to convert them is essential for accurate and reliable results.
