For instance, it's advised to have at least 300ppm postassium in mead. Now, if mead were pure water, this would be easy to understand, but instead, mead has a higher density. Ultimately, there are two possible ways to interpret the term "ppm": mass/volume or mass/mass, as explained here:

As it relates to mead, which definition of PPM is in conventional use? Is it simply milligrams/liter, as it would be if mead were the same as water, or, instead, do we need to consider the density of mead as well when calculating ppm?
Which interpretation is "the standard" will make a significant different when calculating the number of grams of Fermaid-O needed to get a particular PPM of YAN.
