Which is colder, -40 degrees C, or -40 degrees F?
They are equal, that is the crossover temperature of the two scales.
Now, which is heavier, an ounce of feathers or an ounce of gold. How
about a pound of feathers and a pound of gold. No wonder I like the
metric system better.

Water is a special case.

Evening Marshall,

It is numerically correct. Actually it is mg/kg, but since a kilogram

Thanks for explaining all this.
Of course you can for water. The DEFINITION of a liter is 1000 grams of
water. Thus from the definition there are 1,000,000 micrograms in a
liter.
So, ....... a Liter is a unit of weight? I thought it was a unit of
volume? Both I guess.
That is correct, ppm for something is weight/weight, IE for water it
is1 mg/kg of water which equals 1 mg/liter of water.
Ok........ maybe I should accept this. I am used to working with
weights that have a specific value, always, every day.
I suppose this water standard means relatively pure water.
Low, very low, EC. I think some water, especially the mineral water
in TX, CA, and Nevada would mess up the weight of one liter by some
small percent.
It is for the English system. But in the metric system when dealing
with water, volume and weight are interchangeable at STP provided you
know the equalities.
I understand that water should have a standard.
I don't have any of the mineral water to weigh.
Oh well....... I hope to explain a few things that may be of value to
the ones that don't normally work with small units in my next message.
As always, ......... correct me when I am wrong.
Thanks again,
Wayne
