How do I calculate my body fat percentage?

I know that calculating body fat percentage has something to do with total weight, height and age but I'm not sure of the exact formula?

1. Go to msn.com and to the health link they have. If you know how tall you are and how much do you weight now, they do it for you in 1 minute!
2. actually i just had mine done and they did it through blood wrk.it was really interesting and i didnt realize how little fat i had.and they told me its the only sure way to tell.and they can calculate it for you

5. There are formulas, but to get a really good idea, you should get it machine tested. Most gyms have them, and you can get it done at most health centers. This will give you a much better idea. Fish, right ahead of me on another one. And no, I'm not following you.
