So I am looking for a table of the water dissociation constant that is detailed with a .5'F separation, with a pH range of 1 to 14, with a .01 ph resolution or better

The closest thing I can find is tables with a 5 degree C separation, and a .1 does such a table exist?

If not can someone lead me down the right path for finding the formula, I believe that uses temperature, pressure to calculate the values...

Please let me know and thank you.
