Oh, heck, I recall the differences in the 1960's.  One manufacturer 
would talk about a 65K or 131K memory and another would talk about a 
64K or 128K.  I don't believe that, when it comes to numerable items, 
such as the number of words a memory device has (as opposed to a unit 
of measurement) there has ever been any universal agreement.

`When _I_ use a word,' Humpty Dumpty said in rather a scornful tone, 
`it means just what I choose it to mean -- neither more nor less.'

`The question is,' said Alice, `whether you CAN make words mean so 
many different things.'

`The question is,' said Humpty Dumpty, `which is to be master - - 
that's all.'
