h is height over 5 feet (in inches)
YES: you forget the 5 ft. in the calculations.
Robinson: w=108+3.7h
Miller: w=117+3.0h
5'6" tall=6 inches.
w=108+3.7*6=108+22.2=130.2 is the weight using Robinson's formula.
w=117+3*6=117+18=135 is the weight using Miller's formula.
weighs 140 pounds
140=108+3.7h
3.7h=140-108
3.7h=32
h=32/3.7
h=8.65 or 5 ft. 8.65 inches tall using Robinson'e formula.
140=117+3h
3h=140-117
3h=23
h=23/2
h=11.5 or 5 ft. 11.5 inches. tall using Miller's formula.
