Convert 11.5 cm to inches
The Correct Answer and Explanation is :
To convert centimeters (cm) to inches, you can use the conversion factor that 1 inch is equal to 2.54 centimeters. Therefore, to convert centimeters to inches, you can divide the number of centimeters by 2.54.
Calculation:
For 11.5 cm:
[
\text{Inches} = \frac{11.5 \text{ cm}}{2.54 \text{ cm/inch}} \approx 4.528 inches
]
Rounded Result:
When rounded to two decimal places, 11.5 cm is approximately 4.53 inches.
Explanation:
Understanding metric conversions is crucial in various fields such as science, engineering, and everyday applications. The metric system, which includes centimeters, is based on units of ten, making it straightforward for calculations. On the other hand, the imperial system, which uses inches, feet, and pounds, is often used in the United States and a few other countries.
The conversion process stems from the definition of inches and centimeters. The centimeter is a metric unit of length equal to one-hundredth of a meter. In contrast, an inch is defined as 1/12 of a foot. Because these two systems measure length differently, a conversion factor is necessary to switch between them.
When performing conversions, it’s essential to use precise factors to ensure accuracy. In this case, dividing by 2.54 (since 1 inch equals 2.54 cm) provides a direct and simple way to find the equivalent measurement in inches.
Knowing how to convert between these units is particularly useful when reading measurements from tools or devices that may use different systems. For example, a ruler marked in centimeters can be converted to inches for use in a project that requires measurements in the imperial system.
In summary, 11.5 cm is approximately 4.53 inches when converted using the appropriate conversion factor, highlighting the importance of understanding both metric and imperial units in practical applications.
