5. The revised Harris-Benedict equation for a woman's BMR is given by BMR=9.247w+3.098h-4.330a+447.593, where w
is the woman's weight in kilograms, h is her height in centimeters, a is her age in years, and the BMR is measured in
kilocalories per day. For men, the revised Harris-Benedict equation is given by BMR = 13.397w+4.799h-5.677a+88.362
The Mifflin-St. Jeor equation states the new BMR formula as BMR = 10.0w +6.25h-5.0a+s, where s= +5 for men and
s=-161 for women. Use this information to complete parts a and b.
a. All three formulas require metric inputs. Create equivalent U.S. customary formulas for all three formulas by converting
the coefficients of w to pounds and the coefficients of h to inches. For example, using the conversion factor of 1 in. = 2.54
cm, we would multiply 6.25 in the Mifflin-St. Jeor equation by 2.54 to get the revised coefficient of h that would allow us to
input the height in inches.
