AVERAGE VOLUME: Find your weight in pounds. Divide by 62.42 pounds per cubic foot. -or- Find your weight in Kilograms. Change to grams. Divide by .9225 grams per cubic centimeter (ml).

"The surface area may be calculated by multiplying 0.007184 times the weight in kilograms raised to the 0.425 power and the height in centimeters raised to the 0.725 power." [Assume a height of 5'8" (170 cm) and a mass of 150 lb (68 kg).]
