Default KPa to vac/boost conversion?

I searched, but still can't find it. Where do I find out the table, or scale, or whatever, to convert KPa to vac / boost?

kPa * 0.145 = PSI + 14.5.

25 22.1
30 20.7
35 19.2
40 17.7
45 16.2
50 14.8
55 13.3
60 11.8
65 10.3
70 8.9

Edit: it was nice and in two columns before I posted it, but the extra spaces went away. You get the idea though.
