What is the unit of measurement to record a person's height?

1. Centimeters

2. Feet

3. Meters

4. Inches

The correct answer is: Inches

The unit of measurement commonly used to record an individual's height is typically inches, especially in the United States. This is because many medical practices and healthcare environments in the U.S. use the imperial system for height, where measurements are expressed in feet and inches. For example, a person might be recorded as being 5 feet 8 inches tall, which is more familiar and accessible for most individuals in this region. While feet, centimeters, and meters are also valid units for measuring height, inches provides a more standardized and widely accepted format in many healthcare settings. In other parts of the world, centimeters and meters are often used, especially in metric systems, but in the context of this question, inches is the most prevalent choice in practice.
