Why is 14 lbs called a stone?

Let’s share a great old story about why 14 pounds is called stone. A long time ago, people needed a standard weight for trading goods. A strong person found a rock. This rock was easy to lift and carry. They decided this rock would be their standard “stone” weight. When they weighed it accurately, they found it was exactly 14 pounds. So, the weight of that particular (and convenient) rock became known as one stone, fixed at 14 pounds.
