How are heights conventionally measured in the United States?

In the United States, heights are conventionally measured in inches, which is part of the imperial system. This system commonly uses feet and inches for various measurements, including height. For instance, a person's height might be expressed as 5 feet 10 inches, combining both units to provide a clearer understanding of stature within everyday contexts. Using inches aligns with familiar customs and practices in the U.S., where many citizens have a greater awareness and usage of imperial measurements rather than metric units.

While centimeters and millimeters are part of the metric system and used in other countries for height measurement, they are not the standard units in everyday communication in the United States. Consequently, the usage of feet and inches is a more prevalent and recognizable method for measuring height among the populace.
