Converting Pitch Ratio to Cents: from Kyle Gann.
Divide 1200 by the logarithm of 2.
If you use base 10 logarithms (any base is permitted), 1200/log 2 = 3986.3137...
   For any ratio n/p,  the number of cents in the interval is
                         log (n/p) x 1200/log 2
                           If you're using log 10, then
                          cents = log (n/p) x 3986.3137...

Using this formula, we can compare the just scale to the equal tempered scale:
C =  1   = 0 cents               (0)
D =  9/8 = 203.91 cents  (+  4)
E =  5/4 = 386.31  cents     (- 14)
F  =  4/3 = 498 cents           (-  2)
G =  3/2 = 702 cents          (+  2)
A = 5/3  =  884                  (- 16)
B = 15/8  = 1088               (- 12)
C'= 2  =   1200 cents           (0)
