Human weight
From Wikipedia, the free encyclopedia
Weight, in the context of human body weight measurements in the medical sciences and in sports is a measurement of mass, and is thus expressed in units of mass, such as kilograms (kg), or units of force such as pounds (lb). In Britain and Ireland, the unit stone (equivalent to 14 lb or 6.35 kg) is commonly used as well.
A quantity called body mass index (BMI) is often used to express weight relative to height. This is determined by dividing the weight of a person in kilograms by the square of the height in meters.
