In order to calculate the height, in inches, follow the formulas below for each of the bones. Be sure to indicate height not only in the total number of inches, but in terms of feet and inches (i.e., a person who is 62 inches is also described as being 5 feet, 2 inches tall, or 5' 2"). NOTE: The calculations, of course, are different when measurements are in centimeters.

Formula for calculating Body Height (in inches), but only if you use the, "uh, 'merican" system! 
Female 
Male 
Femur 
Height equals (length of femur x 1.94) + 28.7 
Height equals (length of femur x 1.88) + 32 
Humerus 
Height equals (length of humerus x 2.8) + 28.1 
Height equals (length of humerus x 2.9) + 27.8 
Radius 
Height equals (length of radius x 3.3) + 32 
Height equals (length of radius x 3.3) + 34 
In order to calculate the height, in cm, as most of the world does, follow the slightly different formulas below for each of the bones.

Formula for calculating Body Height (in cm) . . . The System EVERYONE ELSE Uses! 
Female 
Male 
Femur 
Height equals (length of femur x 1.94) + 72.9 
Height equals (length of femur x 1.88) + 81.3 
Humers 
Height equals (length of humerus x 2.8) + 71.4 
Height equals (length of humerus x 2.9) + 70.6 
Radius 
Height equals (length of radius x 3.3) + 81.3 
Height equals (length of radius x 3.3) + 86.4 
Now plug in the following numbers into the formula to determine the height to the nearest 1/2 inch (expressed both as inches  x"  and as feet and inches  x' + y") of the deceased:

QUESTIONS:
1. What is the easiest way to determine the gender (using the skeleton) of an individual, and why?
2. What is the easiest way to tell (using the skeleton) whether a teenager is lying about her/his age, and why?
3. Why can determining gender from a skull be difficult?
4. Why should a forensic anthropologist use more than one bone (if possible) to determine the height of an individual?
5. What other issue is important to question four, especially if there is only one bone from which to work?
