How do you convert 5.5 cm to mm?
The Correct Answer and Explanation is:
To convert centimeters (cm) to millimeters (mm), you need to understand the relationship between these two metric units of measurement. The metric system is a decimal-based system used widely around the world, which allows for straightforward conversions based on powers of ten.
In the metric system, 1 centimeter is equal to 10 millimeters. This relationship is crucial for conversions. Therefore, to convert from centimeters to millimeters, you multiply the number of centimeters by 10. The formula for this conversion is:
[
\text{millimeters} = \text{centimeters} \times 10
]
For your specific example of converting 5.5 cm to mm, the calculation would proceed as follows:
- Identify the Value in Centimeters: Here, the value is 5.5 cm.
- Use the Conversion Factor: Multiply the value in centimeters by the conversion factor of 10.
- Perform the Calculation:
[
5.5 \, \text{cm} \times 10 = 55 \, \text{mm}
]
Thus, 5.5 cm is equal to 55 mm.
Understanding this conversion is particularly useful in various fields such as science, engineering, and medicine, where precise measurements are critical. The metric system’s simplicity allows for easy scaling of units, whether you are measuring length, weight, or volume. For instance, knowing that 1 cm equals 10 mm enables you to quickly convert larger measurements (like meters) into smaller ones (like millimeters) without complex calculations.
In practice, whenever you encounter measurements in centimeters that need to be expressed in millimeters, you can apply this straightforward multiplication process. This efficiency is one reason the metric system is favored in scientific and technical contexts, as it minimizes the risk of error associated with conversions between different units.
In summary, to convert 5.5 cm to mm, multiply by 10, resulting in 55 mm.
