There are 3 feet in 1 yard. These are part of the English system of measurement. Other common equivalents of length include 12 inches in 1 foot and 5,280 feet in 1 mile.
Volume and weight measurements are also part of the English system. It developed as people used readily accessible household items and body parts to obtain measurements. For instance, a mile consisted of 1,000 paces, and a gallon, which is an old-fashioned name for "pail," measured a large amount of water. According to Regents, the problem with these procedures was inconsistency. Eventually, the English system became standardized, and people used identical units for measurement.
