The US electronics industry, especially several decades ago, was  
rather stupid when it came to using metric terminology.  They used  
Mfd, mfd, or ufd for microfarad, MMF, uuf, etc for picofarad.  And for  
some reason I never understood, American electronics never used the  
'nano' term.

Since I restore antique radios as one of my hobbies, these  
discrepancies seem less pronounced with prewar European electronics,  
while American manufactures seemed to have each invented their own  
terminology for classifying components.
