Exercise 46 Page 147

Use the conversion factor that 1 foot is roughly equal to 30.48 centimeters.

Practice makes perfect
We want to complete the given statement using < or >. 6ft 300cm To do so, we can convert the units of one term to have the same units on both sides of the inequality. Converting between feet (ft) and centimeters (cm) will involve using a conversion factor. 30.48cm/1ft Multiplying 6ft by this conversion factor will convert it to centimeters.
6ft*30.48cm/1ft
6ft* 30.48cm/1ft
6ft* 30.48cm/1ft
6* 30.48cm/1
6* 30.48cm
182.88cm
This means that 6 feet is less than 300 centimeters, so we will complete the given statement with the inequality symbol <. 6ft < 300cm

Common Conversion Factors
The following tool can be used to help you explore some of the most commonly used conversion factors. Conversions can be made both within or between the Metric System and the Imperial System — which is also known as the U.S. Customary System. Conversions can also be made for different measurement types: length, mass, temperature, time, area, or volume.
Conversion factors between different units of measurement
All across the globe, humans use conversion factors on a daily basis. Want to use a recipe that is written using milliliters? Convert it! Want to compare your height to that of an Olympic athlete? Convert it! You can read more about applications of conversion factors in our original content.
