Is there a calculator for phosphorus content?

Ive searched all around and I can't find a calculator. I found a calculation on Tanyas site
http://www.felinecrf.org/food_data_tabl ... r_analysis

but it seems a lot of them are higher in phos now?

Main ones I'm looking at are:
Turkey pate: As fed values .48 moisture:79.2 calculation: 2.30
Chicken pate: .49 76.8 2.11
Duck pate: .44 76.4 1.86
Beef pate: .38 77.8 1.71
Surf & turf: .67 79.4 3.25

Also, does someone know how to calculate them out to an actual number, for wet content, like on dr lisas chart?

Thank you for any help. I know Ive been asking a lot of nutrition questions, and I appreciate everyone dealing with my many questions. I am just trying so hard to keep Hidey diet regulated and it seems to be getting harder and harder. Theres so many nutritional factors to look at. Im decent in math but all these numbers and calculations are overwhelming and my vet is no help. Every chance they get they're pushing prescription diets on me.

 

% phosphorus in can * (1-% moisture) * grams in can should get you close to what you want.

(1-% moisture) gives you rough % dry matter.
