Body fat % with calipers question

[TUFFTONE]

I took 3 measurements with caliper

Chest 12mm

Stomach-25mm

legs- 18mm

Now how do i find my overall body fat percentage?

Im trying to find out my BF so i can use the 3/Katch-McArdle:Considered the most accurate formula for those who are relatively lean. Use ONLY if you have a good estimate of your bodyfat %.
BMR = 370 + (21.6 x LBM)Where LBM = [total weight (kg) x (100 - bodyfat %)]/100 To get the best results.

I'm not sure.
It might be best to try a couple and see how the results vary. The one with the most inputs should be most accurate.
