Historical roots of these units
The yard traces back to medieveal England, derived from the Saxon gyrd (a measuring stick). King Henry I standardized it as the distance from his nose to thumb. The foot? That’s literally based on human feet, though whose foot varied by region until the 12th century. When industrialization demanded consistency, the 1959 international yard agreement fixed 1 yard as 0.9144 meters, locking the yard-foot relationship we use today.
Square measurements emerged as trade required land area calculations. Builders realized early on that multiplying length by width in matching units prevented errors – hence the birth of dedicated area units like these.
