Default ppm

Various test equipment lists 'ppm (mg/L)'. This does not make any sense to
me since this is mixing a weight with a volume UNLESS one milliliter of
water (or some substance) weighs one gram. 1000 milligrams x 1000
milliliters=1,000,000 mg per liter. Is this true? While I'm at it: does
one ounce of water weigh one ounce?

You got it. One ml of water weighs one gram. We don't use ounces any more
here.

One of the provlems with the English set of units is one liquid ounce of
water does not weigh one ounce. 16 fluid ounces is a pint and 8 pints is a
gallon. 16 ounces is pound and a gallon of water weighs 8.33 pounds instead
of 8.

yes. water is the standard of 1 cc = 1 ml = 1 gram
it is soooo much easier to use %. that is grams per 100 ml.
so 3% is 3 grams of something in 100 ml or 0.1 liter

That's 20 fluid ounces to a pint, at least in England :-)

Which is lighter, a pound of filter beads or a pound of feathers?

Now your just confusing the issue, since you guys have money called a
pound which probably doesnt weigh an ounce or a gram, but which can probably
be exchanged for a pint either Am or Eng.

Me confusing the issue... it depends on which side of the pond you are
:-)

As for the money pound fifty of them can weigh just slightly more than
one of them or one of them can weigh hundreds of times more than fifty,
take your pick :-)

One of them certainly couldn't be exchanged for a pint of some common
things though any more. I remember a landlord telling me a pint would
never be a pound because people wouldn't stand for it, showing my age
now :-)
