I believe that "stone" is actually the unit of weight. But given that the 
word was likely created before people understood there's a difference, and 
given that "pounds" is always the same force in Earth's gravity field, and 
given that it doesn't really get used in the scientific field where you wind 
up in situations where mass and force are actually important to distinguish, 
... no, I don't think so.

So when the instruction book for your car tells you how much pressure to put 
in your tires, do they really say "put 206,000 newtons of pressure in your 
tires"?
