Maybe something like that (should work in MySQL):
SELECT CASE
WHEN weight IS NULL THEN NULL
WHEN weight < 16 THEN CONCAT( weight , ' oz' )
WHEN weight < (16*14) THEN CONCAT( weight / 16 , ' lb' )
WHEN weight < (16*14*2) THEN CONCAT( weight / (16*14) , ' st' )
WHEN weight < (16*14*2*4) THEN CONCAT( weight / (16*14*2) , ' qtr' )
WHEN weight < (16*14*2*4*20) THEN CONCAT( weight / (16*14*2*4) , ' cwt' )
ELSE CONCAT( weight / (16*14*2*4*20), ' ton' )
END
FROM weights_table
ORDER BY weight
