By 1985, Stone was an official unit in the UK. Since then, its use is for business purposes (for example, product labeling, technical data ) by the Weights and Measures Act expressly prohibited. The same applies to the above used to explain units and Dram (long) ton. In countries is where British English is spoken, as in the United Kingdom, Ireland, Australia or New Zealand, but it is still customary to quote the human body weight in stone ( "I have lost two stone five" - "I have two Stone and five pounds (15 kg) decreased "). Stone has as an unofficial unit of human body weight a meaning similar to the obsolete and abolished kilocalorie in German as a unit for the energy content of ( human ) food or PS for performance, especially for internal combustion engines.

In part, the weight of wrestlers, boxers and jockeys will be given in Stone and pounds, which is being increasingly replaced by an indication in pounds.

If Stone is used as a unit with a preceding number, use British native speakers no plural -S, without number, however, already ( " What is your weight in stones and pounds? " - "What is your weight in stone and pounds? ").
