A liter is one cubic decimeter of anything. One cubic decimeter of water is
equal to one deciliter of water, and contains 1000 ml of water.
One mililiter of DISTILLED water weights one milligram.
A liter is a unit of volume.

At 0 deg C or 32 Deg F water isn't water any more.

Water is a special case.

Evening Marshall,

Thanks for explaining all this.

So, ....... a Liter is a unit of weight? I thought it was a unit of
volume? Both I guess.

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.

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
