Chapter 1, Problem 98b
Perform each unit conversion. b. 116 ft to cm
Verified step by step guidance1
Identify the conversion factors needed: 1 foot (ft) is equal to 30.48 centimeters (cm).
Set up the conversion equation using the conversion factor: \( 116 \text{ ft} \times \frac{30.48 \text{ cm}}{1 \text{ ft}} \).
Cancel out the units of feet (ft) to leave the desired unit of centimeters (cm).
Multiply the numerical values: 116 by 30.48.
The result will give you the length in centimeters.

Key Concepts
Here are the essential concepts you must grasp in order to answer the question correctly.
Unit Conversion
Unit conversion is the process of converting a quantity expressed in one unit to another unit. This involves using conversion factors, which are ratios that express how many of one unit are equivalent to another. For example, to convert feet to centimeters, one must know that 1 foot is equal to 30.48 centimeters.

Metric System
The metric system is an internationally recognized decimal-based system of measurement. It includes units such as meters for length, grams for mass, and liters for volume. Understanding the metric system is essential for conversions, as it provides a standardized framework that simplifies the process of converting between different units, such as feet to centimeters.
