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

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?
