What is the length equivalent for one yard in inches?

One yard is equivalent to 36 inches because a yard is defined as exactly 3 feet, and each foot contains 12 inches. Therefore, to convert yards to inches, you multiply the number of yards by the number of inches in one foot:

1 yard = 3 feet

1 foot = 12 inches

So, 1 yard = 3 feet × 12 inches/foot = 36 inches.

This understanding highlights the direct relationship between yards and inches based on the standard units of measurement in the Imperial system. Consequently, the correct answer reflects this conversion accurately.
