Yard: The yard is a unit of length used in the United States and the United Kingdom. It is equal to three feet or 0.9144 meters. Yards are often used in construction and landscaping.
A "nail" is a traditional unit of length used for measuring cloth or fabric, particularly in some regions of India. The nail is based on the width of a finger, and it is typically equal to approximately 2.25 inches or about 5.715 centimeters.
Nails were historically used in the textile and clothing industry to measure the width of cloth or fabric. However, like many other traditional units of measurement for textiles, the nail has largely been replaced by more standardized and metric units, such as inches, centimeters, or meters, in modern times.
