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"?
