60 inches is equivalent to 5 feet in the U.S. customary and Imperial measurement systems. In these systems, 12 inches is the equivalent of 1 foot.
Inches and feet are units of measurement in the U.S. customary and Imperial measurement systems. The U.S. system grew out of the Imperial system, which was originally used in Britain. The names of the units are based on the various, less standardized ways in which people used to measure lengths, distances, and weights. The words "pound," "foot," and "gallon" were still used, but their values would change depending on context. As trade increased and spread across the world, it was decided that a more formal, concrete system of measurement was necessary, and the Imperial system was created. However, most modern-day countries have adapted to the metric system, which is formally known as the International System of Units.
