A kilogram is about 2.2 pounds and a meter is about 39 inches. For example, if you weigh 80 Kg and your height is 1.6 meters (160 cm), then your BMI is 80 / (1.6 x 1.6) = 31. There are lots of web sites with BMI calculators so you just enter your height and weight and it tells you.

Is a Bmi of 20 underweight?

A bmi of 20 is not underweight, but is still a lower than average bmi. For the average adult, under 18.5 is underweight, and 18.5 to 24.9 is a healthy weight.

What percent of the human body is penis?

Human body volume is approximately equal in L to the weight in kg (see: the Internet)

e.g. a 180 lb male would be about 80kg, which is roughly equivalent to 80 L

Now, we need a little math for the 2nd part: penile volume

Recall the volume of a cylinder is equivalent to the area of a circle multiplied by the height, or

V = (pi)r2h

We can estimate area from circumference: 2(pi)r. If the average human penis girth (circumference) is about 12cm, that means the radius would be somewhere around 2 (12 / 2 / pi).

The average length (height) of the penis is about 15 cm, so with all of that, we have:

V = pi * (2)2 * 15 = ~190 cm3

Now, we simply divide this by the original volume (80 L, or 80,000 cm3):

190 / 80,000 = .002375, or .2%

What should an adult's bone density be?

That depends on a lot of things. The bone density peaks at about age 30 and the tests designed to look for low density compare the measures to the normal for a woman of that age.

The result is usually expressed as a "T score" which is the number of standard deviations above or below average for 30 year old woman. For women, a T score of less than -1.0 indicates "osteopenia" and osteoporosis is when the T score is -2.5 or less. This scoring system is not appropriate to apply to men.

When to treat with medications is more complicated and depends on a lot of factors. It can be reasonable to give medications to someone with osteopenia and it can also be reasonable to not give medications to other people with full blown osteoporosis.

A more direct answer to your question would be to see if the report also lists a "z-score". This is the density as compared to others of your own gender and age. 0 is average with negative numbers being below average.

Why does the Body Mass Index say im underweight even though my body fat percentage is healthy?

Body mass index should be used as a general guideline. It isn't the most accurate thing to go by, and body fat percentage is much more of a health indicator. You probably just have a smaller frame size than others. Don't worry!

Why do you float when you lay on your back in the water?

This happens because your body is less dense than water. It is the very same reason why a helium filled balloon will float upward in air. Helium is less dense than air, and so the more dense air settles under the balloon and moves it up; the balloon is 'seeking' the surface of the air mass that it is floating in.

Another way of thinking about this: If you could measure out the amount of water that weighs exactly the same as your body weight, you will find that the volume of that water is less than the volume of your body. Same weight in a smaller volume-- that means the water is more dense than your body. The density of water is really called specific gravity, but the concept is the same.

__________________

NOTE: This turns out to be very useful as a way of measuring over-all body fat, or the Body Mass Index. Some people can be standing in 3 or 4 feet of water, exhale the air from their lungs as completely as possible, and have time to float down to the bottom of the pool and lay there for a moment before coming up for air. Others cannot do this, no matter how hard they exhale. The difference is the amount of body fat. body fat is less dense than muscle, so it works to keep the body at or near the surface.
