The "pennyweight" is 1/20th of a troy ounce, not the std ounce.  It should = 24 grains.

Add "dwt" as an abbreviation for "pennyweight".  This is commonly used in the mining community.

Also "troy ounce" or perhaps "troz" should be added as a synonym for "apounce". 

troyounce               apounce
troz                    apounce
pennyweight             1|20 troz (or apounce)
pwt                     pennyweight
dwt                     pennyweight

>How-To-Repeat:
         
>Fix:
Delete pennyweight = 1|20 oz

troyounce               apounce
troz                    apounce
pennyweight             1|20 troz (or apounce)
pwt                     pennyweight
dwt                     pennyweight
