I agree with powernoodle and *very* much agree with Lunal_Tic. The metric system is simply the way to go.
Try dividing 4 feet , 7 7/32" into 5, or adding 4 1/16 feet and 5 7/32" /ubbthreads/images/graemlins/icon3.gif
Go the metric way, and it's:
140.25 cm /5= 28.05
3.25 + 4.25= 7.50
etc.
I don't buy the whole "it's too expensive to implement" song, so I'll stop my rant here and sign off! Cheerios,
