Body weight
From Wikipedia, the free encyclopedia
Although some people prefer the less-ambiguous term body mass, the term body weight is overwhelmingly used in daily English speech as well as in the contexts of biological and medical sciences to describe the mass of an organism's body. Body weight is measured in kilograms throughout the world, although in some countries people more often measure and describe body weight in pounds (e.g. United States and sometimes Canada) or stones and pounds (e.g. among people in the United Kingdom) and thus may not be well acquainted with measurement in kilograms. Most hospitals, even in the United States, now use kilograms for calculations, but use kilograms and pounds together for other purposes. (1 kg is approximately 2.2 lb; 1 stone (14 lb) is approximately 6.4 kg.)
The term is usually encountered in connection with:
- food and feeding behaviour
- normal and abnormal growth and development
- the physiological and hormonal control of ingestion and digestion
- foraging for food in animals
- hunger and other motivations to eat
- problems in regulating body weight, often resulting in obesity
- eating disorders such as anorexia nervosa and bulimia nervosa
- effects of disease
- athletic competitions where the participants are classified according to their body weight
