In boxing, a weight class is a measurement weight range for boxers. The lower limit of a weight class is equal to the upper weight limit of the class below it. The top class, with no upper limit, is called heavyweight in professional boxing and super heavyweight [1] in amateur boxing. A boxing match is usually scheduled for a fixed weight class ...
By doing this, doctors can track a child's growth over time and monitor how a child is growing in relation to other children. There are different charts for boys and girls because their growth rates and patterns differ. For both boys and girls there are two sets of charts: one for infants ages 0 to 36 months and another for ages 2 and above.
The height, weight, and head circumference of a child can be compared to the expected parameters of children of the same age and sex to determine whether the child is growing appropriately. Growth charts can also be used to predict the expected adult height and weight of a child because, in general, children maintain a fairly constant growth curve.
The 2000 CDC growth charts - a revised version of the 1977 NCHS growth charts - are the current standard tool for health care providers and offer 16 charts (8 for boys and 8 for girls), of which BMI-for-age is commonly used for aiding in the diagnoses of childhood obesity. [1]
The weight division system is different in each organisation, so the kickboxing weight divisions of some international organizations vary: International Kickboxing Federation (IKF), welterweight (Pro & Amateur) 142.1–147 lb or 64.5–66.7 kg. [21] International Sport Karate Association (ISKA), welterweight 142.1–147 lb or 64.5–66.7 kg. [22]
For a variety of reasons (largely historical), weight classes of the same name can be of vastly different weights. For example, a boxing middleweight weighs up to 72 kg (160 lb), an ISKA middleweight upper limit is 75 kg (165 lb), and a K-1 middleweight upper limit is 70 kg (154 lb).

A featherweight boxer weighs in at a limit of 126 pounds (57 kg). In the early days of the division, this limit fluctuated. The British have generally always recognized the limit at 126 pounds, but in America the weight limit was at first 114 pounds. An early champion, George Dixon, moved the limit to 120 and then 122 pounds. Finally, in 1920 ...
