Yeah, I know it's theoretically 32*, or maybe it's not. Is it 32.5*, or more like 33*, or even warmer than that?

I have to tweak a digital down some, and it occurred to me since I am adjusting a xxx.x resolution thermometer, that maybe I should ask instead of assume the temp is exactly 32*.

And how much does water purity matter, not talking about sea water or something that rich of a solution?

Does elevation affect the temp? I am just below 1000' above seal level, but it occurred to me that elevation is an issue for those in the mountains...

If you put a bunch of ice cubes in a minimum amount of water, just what temp is it going to be?

I've always used 32F for a glass of ice with little liquid water in it.

Your temperature estimation device will be fairly close then... it's all relative to your measuring device anyway.

32 if it's mostly ice and water filling the gaps.

The best method is to make up a crushed ice and water solution. That's effectively 32 deg. F. Even if it's off by .1 or .2 degrees, that's still at or below the margin of error on normal thermometers.

32F, 0C - it takes the heat of fusion to make ice so the temperature doesn't change but more heat is released as it changes phase - make sense?

It can't be exactly 32. If it was then it would not be water. I would say it depends on the amount of ice to water and how long they have been mixed together. It is probably under 33 though. Also the amount of TDS (total disolved solids) in the ice will make a difference. I don't think elevation will matter though. I think elevation only matters with boiling but I could be wrong with that.

The freezing point of liquid water is 32F. The melting point of solid water is 32F. Without considering temperature equilibrium throughout any given vessel of ice water, it's temperature will effectively remain at 32F until all ice is melted. This is due to the latent heat of melting. This is what mandoman is getting at. Because temperature can vary in a vessel (warm spots), in the real world, Bobby_M has it correct.

This thermometer is used only for cheese, so it only has to read up to 108*, but mainly at mid to upper 80's. But at this small of a temp range, a degree or two is worth knowing.

I guessed it would be about 32.5*....as the water is getting cooled by the surface of cubes, but getting warmed by the surface of the container.

lehr, you're on >ignore<.

It does, but not in any practical sense. The variation is less than one hundredth of a degree per atmosphere of decrease in
pressure.

Yeah, one of the crazy properties of water. Also, that its solid form is less dense than its liquid form, making ice float.
