The Body Fat Percentage is a measure of fitness level, since it is the only body measurement which directly calculates a person's relative body composition without regard to height or weight. It is the total mass of fat divided by total body mass; body fat includes essential body fat and storage body fat. Essential body fat is necessary to maintain life and reproductive functions. The percentage of body fat for women is greater than for men, due to the demands of childbearing and other hormonal functions.
The following formula is used for adults : BF%=(1.20*BMI)+(0.23*AGE)-(10.8*SEX)-5.4.
For children this formula is used: BF%=(1.51*BMI)-(0.70*AGE)-(3.6*SEX)+1.4, where:

• BMI = body mass index
• AGE = age
• SEX = sex

The following table shows average percentages for men and women.
