With the healthstatus.com calculator and rounding up on all the half inch #s -

your body fat percentage is estimated to be 21.31 % using the U.S. Army body fat algorithm, or 14.18 % using the U.S. Marine body fat algorithm, or 16.56 % using the U.S. Navy body fat algorithm, or 15.84 % using the formula developed by the YMCA.

These methods are not as accurate as a water displacement test, but is usually within 1-3% for most people. If you have a very small waist, it will show a low value. On the other hand, if you carry all your extra weight around your middle, you may have an elevated percentage.

I guess I'll stick with the mirror method.

I finally did the calculation and it's a lot better than my tanita scale (which I know I shouldn't count on anyway)! 27ish %.

I'm missing something:

Factor 1 = (125*.732)+8.987 = 100.487
Factor 2 = 6/3.14 = 1.91
Factor 3 = 27*.1257 = 4.24
Factor 4 = 36*.249 = 8.96
Factor 5 = 8.25*.434 = 3.58
Factor 1 + 2 - 3 - 4 + 5 = 92.78

You're missing calculating your body fat weight (total body weight minus lean body mass) and then multiplying your body fat weight by 100 and dividing that by your total body weight. I come up with 26% (rounded up) for you.

well than I must have done something wrong, because based on my last caliper test I had 13%, and 111 of my 127 (at that time) that was lean mass. Since then the scale hasn't moved, but I've added more lean mass.

Where the heck is my waist anyway? Since I am one of those men that is pretty lean except for a belly, it's hard to tell. I wear a size 36 pants, but my belly extends a good bit past that!

very interesting, can't wait to try it out.

Well, it's possible *I* did something wrong. I just plugged my numbers into an excel spreadsheet and then changed my numbers for yours. I did think it was strange since I'm about 35 lbs heavier than you.

Thanks so much. I created an excel spreadsheet with this formula and I'll be using it monthly.

I wonder if the women's waist measurement should be "smallest part of waist" and not "at navel". The smallest part of my waist is above my navel.

I've done it again and again and just keep coming up with the same numbers, then i plugged it into an online one and still got the same number . . . my proportions must be all out of whack.
