RAW MATERIAL BAR STOCK

we purchase quite a bit of raw material (bar stock). our stocking unit of 
measure is linear feet. BPCS wants all transaction qtys to be to three decimal 
positions. but the tape measures are in feet and inches. so if we want to 
transact a bar that measures 3 feet 7 inches, what should we enter into BPCS as 
the qty? if i convert to feet with decimal positions i get 3.583333 feet. we 
could do this conversion (i'd like to think that our material movers can do 
this).
but what do we enter if it is 7 bars each 3 feet 7 inches? to do this is it 
25.08333 feet?

to make this conversion easier, has anybody ever seen a tape measure that was 
measures in feet and decimal portions of a foot. in other words, a tape measure 
that we could read 3.58 feet directly from the tape measure?
