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 it is still measured in pounds (e.g. United States) 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.)

A number of ways to estimate weight in children have been developed. They include: Broselow tape, Leffler formula, and Theron formula.4 The Broselow tape is based on length with weight read from the appropriate color area. The Leffler formula is used for children 0-10 years of age.4 In those less than 1 year old it is (weight in kg) = (age in months)/2 + 4 for those 1-10 years it is (weight in kg) = 2*(age in years) + 10.4 The Theron formula is (weight in kg) = exp(0.175571*age in years + 2.197099).4 Sports usage

Participants in sports such as boxing, mixed martial arts, wrestling, rowing, judo, and weight-lifting are classified according to their body weight, measured in units of mass such as pounds or kilograms. See, e.g., wrestling weight classes, boxing weight classes, judo at the 2004 Summer Olympics, boxing at the 2004 Summer Olympics.
