Well. if there ratio fits, then they are linear dependend of the real 
latitude/longitude. So why "break" the coding? Just go out, measure some more 
points with your working unit and calculate 

factor1 = 373101418 / 44.477135
factor2 = 219065058 / 26.114385
factor3 = ...
...
factor = median(factor1, factor2, ...)

and then

lon = measured_first_uint * factor
lat = measured_second_uint * factor


Ciao, Imi.
