based on a sample aged 17-25. (reference: Sloan, A.W., Burt A.J., Blyth C.S.: Estimating body fat in young women., J. Appl. Physiol. (1962);17:p967-970)

Skinfold measurements are taken from two sites: Triceps - measure vertically on the back of the arm midway between the top of shoulder point (Acromial Process) and the elbow (Olecranon Process). Calf - measurement taken inside (medial) side of the right lower leg at the greatest calf girth.

For ages 30-39 females: D = 1.1423 - (0.0632 X L)

Using Metric Measurements (cm) This is believed to be the metric version of the Navy body fat formula. Note, all measurements are in centimeters to the nearest 0.5 cm, including height. males: % body fat = 495/(1.0324-0.19077(log(waist-neck))+0.15456(log(height)))-450 females: % body fat = 495/(1.29579-0.35004(log(waist+hip-neck))+0.22100(log(height)))-450

All circumferences are in inches. than 240 minutes of vigorous activity per week. Younger Women (17-26 years): % body fat = (abdominal x 1.34) + (thigh x 2.08) – (forearm x 4.31) – 19.6 [or 22.6] Older Women (over 26 years): % body fat = (abdominal x 1.19) + (thigh x 1.24) – (calf x 1.45) – 18.4 [or 21.4]

For ages 30-39 males: D = 1.1422 - (0.0544 X L)

Skinfold measurements are taken from two sites: Triceps - measure vertically on the back of the arm midway between the top of shoulder point (Acromial Process) and the elbow (Olecranon Process). Calf - measurement taken inside (medial) side of the right lower leg at the greatest calf girth.

This is the formula (Hodgdon and Beckett, 1984) that was taken from the Navy website, and is seen elsewhere on the internet. Note, all measurements are in inches (measured to the nearest 1/4 inch), including height. males: % body fat = 86.010 x log10(abdomen - neck) - 70.041 x log10(height) + 36.76

All circumferences are in inches. Younger Men (17-26 years): % body fat = (upper arm x 3.70) + (abdominal x 1.31) – (forearm x 5.43) – 10.2 [or 14.2] Older Men (over 26 years): % body fat = (buttock x 1.05) + (abdominal x 0.90) – (forearm x 3.00) – 15.0 [or 19.0] ( ( {Hip (cm):39} / 2.54 ) * 1.05 ) + ( 0.90 * ( {Waist (cm):38} / 2.54 ) ) - ( ( {Forearm (cm):33} / 2.54 ) * 3.00 ) - 19.0
