Weight (in non-scientific affairs)

Worldwide use:

The stone is now used almost exclusively in the UK and Ireland, as a popular – if informal – way of expressing a person’s weight. The stone has not been officially recognised as a unit of weight in the UK since 1985.

A British or Irish person will commonly express their weight in stone and pounds (eg. 12 st 6 lbs) instead of purely in pounds as would be the case in the United States (174 lbs).

The stone is still habitually used to express human bodyweight in some sports in the UK and Ireland, such as boxing and wrestling.

The stone is also used in horse racing to describe the weight that a horse has to carry (not necessarily just the jockey, this weight can also include penalties and suchlike).

Definition:

A stone is a unit of weight equal to 14 pounds averdupois (or international lbs). By turn, this makes a stone equivalent to 6.35029kg.

Origin:

The name ‘stone’ derives from the practice of using stones as weights, a common practice worldwide for two millennia or more.

The actual unit of the stone was commonly used as a measure of weight for trade purposes across Europe until the 19th century when most countries adopted the metric system, however, the actual weight of the stone varied from country to country, region to region, and even depending on what was being weighed or traded.

In 1389 in England a stone of wool was defined as weighing fourteen pounds, and although a stone of other materials could weigh significantly more or less (in pounds), the stone in general usage became accepted as weighing equal to 14 lbs.

Common references:

A 5ft 8in (173cm) tall woman of average build would be expected to weigh between eight and twelve stone.

A 6ft 0in (183cm) tall man of average build would normally weigh between ten and thirteen stone.
