A combination of table and formula is given in

D.W. Robinson and R.S. Dadson,
'A re-determination of the equal-loudness relations for pure tones',
British Journal of Applied Physics, 7, 1956, 166-181

These data are generally regarded as being more accurate than those of
Fletcher and Munson.  Of course both sources apply only to pure tones in
otherwise silent free-field conditions, with a frontal plane wave etc
etc.

Computer models of loudness are available from several sources.  A
version of Moore, Glasberg and Baer's 1997 model, for Macintosh, is on
my website.
