Introduction

In mathematics, conversion factors are used to convert between different units of measurement. They are essential in various fields, including science, engineering, and finance. In this article, we will discuss conversion factors and identify the expressions that are written as conversion factors.

What are Conversion Factors?

Conversion factors are ratios that express the relationship between two different units of measurement. They are used to convert a quantity from one unit to another. For example, if we want to convert a length from meters to centimeters, we can use the conversion factor 1 m = 100 cm.

Examples of Conversion Factors

Here are some examples of conversion factors:

1 m = 100 cm
1 L = 1000 mL
1 kg = 1000 g
1 in. = 2.54 cm

Selecting the Correct Conversion Factors

Now, let's go back to the original question and select the expressions that are written as conversion factors.

A. $1 \, \text{cc} = 1 \, \text{mL}$

This expression is a conversion factor because it expresses the relationship between two different units of measurement, cubic centimeters (cc) and milliliters (mL).

B. $\frac{2.54 \, \text{cm}}{1 \, \text{in.}}$

This expression is also a conversion factor because it expresses the relationship between two different units of measurement, centimeters (cm) and inches (in.).

C. $1 \, \text{m} = 10^2 \, \text{cm}$

This expression is not a conversion factor because it is not a ratio. It is an equation that expresses the relationship between two different units of measurement, meters (m) and centimeters (cm).

D. $1 \, \text{lb} = 16 \, \text{oz}$

This expression is a conversion factor because it expresses the relationship between two different units of measurement, pounds (lb) and ounces (oz).

Conclusion

In conclusion, conversion factors are essential in mathematics and are used to convert between different units of measurement. By understanding what conversion factors are and how to identify them, we can solve problems and make calculations more efficiently.
