Reference charts for adult head circumference also generally feature homogeneous samples and fail to take height and weight into account. [ 6 ] One study in the United States estimated the average human head circumference to be 57 centimetres ( 22 + 1 ⁄ 2 in) in males and 55 centimetres ( 21 + 3 ⁄ 4 in) in females.
the ratio of hip circumference to shoulder circumference varies by biological sex: the average ratio for women is 1:1.03, for men it is 1:1.18. [9] legs (floor to crotch, which are typically three-and-a-half to four heads long; arms about three heads long; hands are as long as the face. [10]
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 ...
v. t. e. A person's waist-to-height ratio ( WtHR ), occasionally written WtHR or called waist-to-stature ratio ( WSR ), is defined as their waist circumference divided by their height, both measured in the same units. It is used as a predictor of obesity-related cardiovascular disease. The WHtR is a measure of the distribution of body fat.
A review published in the 2007 issue of BJU International showed the average erect penis length to be 14–16 cm (5.5–6.3 in) and girth to be 12–13 cm (4.7–5.1 in). The paper compared results of twelve studies conducted on different populations in several countries.
The waist–hip ratio or waist-to-hip ratio ( WHR) is the dimensionless ratio of the circumference of the waist to that of the hips . This is calculated as waist measurement divided by hip measurement ( W⁄H ). For example, a person with a 75 cm waist and 95 cm hips (or a 30-inch waist and 38-inch hips) has WHR of about 0.79.
The adult human brain weighs on average about 1.5 kg (3.3 lb). [ 1] In men the average weight is about 1370 g and in women about 1200 g. [ 2][contradictory] The volume is around 1260 cm 3 in men and 1130 cm 3 in women, although there is substantial individual variation. [ 3] Yet another study argued that adult human brain weight is 1300-1400 g ...
v. t. e. Body mass index ( BMI) is a value derived from the mass ( weight) and height of a person. The BMI is defined as the body mass divided by the square of the body height, and is expressed in units of kg/m 2, resulting from mass in kilograms (kg) and height in metres (m). The BMI may be determined first by measuring its components by means ...
