Human body weight - wikipedia Human body weight Human body weight refers to a person 's mass or weight. Body weight is measured in kilograms, a measure of mass, throughout the world, although in some countries such as the United States it is measured in pounds, or as in the United Kingdom, stones and pounds. Most hospitals, even in the United States, now use kilograms for calculations, but use kilograms and pounds together for other purposes. Strictly speaking, body weight is the measurement of weight without items located on the person. Practically though, body weight may be measured with clothes on, but without shoes or heavy accessories such as mobile phones and wallets and using manual or digital weighing scales. Excess or reduced body weight is regarded as an indicator of determining a person 's health, with body volume measurement providing an extra dimension by calculating the distribution of body weight.

There are a number of methods to estimate weight in children for circumstances ( such as emergencies ) when actual weight can not be measured. Most involve a parent or health care provider guessing the child 's weight through weight - estimation formulas. These formulas base their findings on the child 's age and tape - based systems of weight estimation. Of the many formulas that have been used for estimating body weight, some include the APLS formula, the Leffler formula, and Theron formula. There are also several types of tape - based systems for estimating children 's weight, with the most well - known being the Broselow tape. The Broselow tape is based on length with weight read from the appropriate color area. Newer systems, such as the PAWPER tape, make use of a simple two - step process to estimate weight : the length - based weight estimation is modified according to the child 's body habitus to increase the accuracy of the final weight prediction. The Leffler formula is used for children 0 -- 10 years of age. In those less than a year old it is m = 1 2 a m + 4 ( displaystyle m = ( \tfrac ( 1 ) ( 2 ) ) a_ ( m ) + 4 ) and for those 1 -- 10 years old it is m = 2 a y + 10 ( displaystyle m = 2a_ ( y ) + 10 ) where m is the number of kilograms the child weighs and a and a respectively are the number of months or years old the child is. The Theron formula is m = e 0.175571 a y + 2.197099 ( displaystyle m = e ^ ( 0.175571 a_ ( y ) + 2.197099 ) ) where m and a are as above. Fluctuation Body weight varies throughout the day, as the amount of water in the body is not constant. It changes frequently due to activities such as drinking, urinating, or exercise. Professional sports participants may deliberately dehydrate themselves to enter a lower weight class, a practice known as weight cutting. Ideal body weight Ideal body weight ( IBW ) was initially introduced by Devine in 1974 to allow estimation of drug clearances in obese patients ; researchers have since shown that the metabolism of certain drugs relates more to IBW than total body weight. The term was based on the use of insurance data that demonstrated the relative mortality for males and females according to different height -- weight combinations. The most common estimation of IBW is by the Devine formula ; other models exist and have been noted to give similar results. Other methods used in estimating the ideal body weight are body mass index and the Hamwi method. The IBW is not the perfect fat measurement as it does not show the fat or muscle percentage in one 's body. For example, athletes ' results show that they are overweight when they are actually very fit and healthy. Machines like the dual - energy X-ray absorptiometry ( DXA ) can accurately measure the percentage and weight of ( fat, muscle, bone ) in a body. Devine formula The Devine formula for calculating ideal body weight in adults is as follows : Male ideal body weight = 50 kilograms ( 110 lb ) + 0.9 kilograms ( 2.0 lb ) × ( height ( cm ) − 152 ) Female ideal body weight = 45.5 kilograms ( 100 lb ) + 0.9 kilograms ( 2.0 lb ) × ( height ( cm ) − 152 ) Hamwi method The Hamwi method is used to calculate the ideal body weight of the general adult : Male ideal body weight = 48 kilograms ( 106 lb ) + 1.1 kilograms ( 2.4 lb ) × ( height / cm − 152 ) Female ideal body weight = 45.4 kilograms ( 100 lb ) + 0.9 kilograms ( 2.0 lb ) × ( height / cm − 152 ) Usage Sports Participants in sports such as boxing, mixed martial arts, wrestling, rowing, judo, Olympic weightlifting, and powerlifting 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. Medicine Ideal body weight, specifically the Devine formula, is used clinically for multiple reasons, most commonly in estimating renal function in drug dosing, and predicting pharmacokinetics in morbidly obese patients.
