It's awesome swimming in the salted water in our pool...

It should be about 5 ppt salt, about the same as the bay, up in the
North East spur past Baltimore (or the Potomac around Port Tobacco).


Huh? Sea water is about 3.7 percent salt or 35,000 parts per million.
The salt in a salt water system pool is in the 2,800 to 3,600 parts per
million range.

It's *not* salt water.


They usually use parts per thousand when they talk about bays and
oceans. Push that decimal place over 3 and we are on the same page.


"ppt" is parts per trillion, not parts per thousand.



Not the way Greg has been using it. I'm grinning because in many cases your numbers are pretty
close, if you divide yours by a thousand or multiply Greg's by a thousand. However, you are right in
that 'ppt' normally means 'parts per trillion', at least according to Wikipedia: "Commonly used are
ppm (parts-per-million, 10–6), ppb (parts-per-billion, 10–9), ppt (parts-per-trillion, 10–12) and
ppq (parts-per-quadrillion, 10-15)."

I'll bet the 'parts per thousand' is something used locally down there in Florida - where folks are
just a lot smarter than those of us up north.



To make it even more confusing, parts per thousand is usually expressed
as "parts per mil".


If I'd just seen the "parts per mil", I'd be thinking 'parts per milliliter'.

Or ML

Quit trying to confuse me.

I just ordered one of these for my grandson who's on his way to becoming an Eagle Scout. It should
happen in about two more years.

I'd seen this one, but decided the cost was a bit high!

Maybe I can get the side plate engraved.



Maybe you should reconsider and buy him some books.

I'll be doing that also. I can't afford to pay for college for all the grandkids, but I might could
buy their books for them. A laptop has made a nice graduation present for nieces and nephews who've
gone to college. The last one got a Mac. Don't remember which one. We put it in a 'Refurbished HP'
box. She was blown away when she opened the HP box only to find a Mac box.

So, your snarky little comment got a nice reply, eh?
