Stone

📖A stone is a unit of mass equal to 14 pounds (approximately the weight of a bowling ball). It is commonly used in the UK and Ireland to measure people's weight, but also for weighing other goods.

💡 Did you know that the stone as a unit of measure can be traced back to ancient times? The ancient Egyptians used stones as weights for trade, and the practice continued throughout history. The stone was even used in medicine during the Middle Ages to measure patients' weight.
