Bodyfat Measurement?

I have an Accu Measure bodyfat caliper that I used awhile back. Does anyone have a website with the formula to convert the measurements into my bodyfat percentage?

I know about that website but theres a site that you could enter in the measurements on stomach, chest, thigh and it calculates your bodyfat. It’s a little more accurate than that chart.

anyone?

How 'bout this one:

exaclt what I was looking for. Thanks.
