Please forgive me if this is obvious, but is it possible to convert 2” of mercury to X lbs. of boost, as in a turbo?  I’d love to see the math if anyone can show me.

29.921 258 3 inch of mercury [0 °C] = 14.695 950 254 pound/square inch = standard atmospheric
31.921 258 3 inch of mercury [0 °C] = 15.678 258 558 pound/square inch
19 pound/square inch = 38.684 392 494 inch of mercury [0 °C] (your basic 5pounds of boost)

(I could be wrong about this.)
