Yard (yd)
The yard, symbolized as yd, is an Imperial and US customary unit of length equal to 3 feet or exactly 0.9144 metres. Legend attributes its historical origin to the distance from King Henry I's nose to the tip of his outstretched thumb, though it was officially standardized internationally in 1959. The yard remains in widespread official use for road signage, sports field dimensions, and textile sales across the United Kingdom and the United States.
