Default Ever tried to calibrate your thermometer by putting it under your tongue?

I just tried it and it looks like my thermometer may be a degree low. Be careful with it, mine is very sharp and could do some damage in there!

Body temp is not a reliable source. The 98.6 deg F is an average of human body temp. My SWMBO normally runs about 99.2. I run at 98.4. It's a good ballpark starting point, but not a true "calibration". That takes more scientific methods. But keep in mind, as much as some try to, homebrewing is not an exact science. It is all about the trial and error and finding what works for you. IMHO, if you take it too seroiusly, you will overanalize and endup ruining your beer. Just enjoy the brewday. So what if your mash temp is a few degrees off, its about the experiance.
Remember the mantra.

I typically run a little low unless I'm sick, but I figured it would be a good way to make sure it wasn't running like 5 degrees or more off.

Why don't you just put ice in a cup fill it with cold water let it sit for a few minutes then just stick it in... that is 32F or on the high side, get your water to a rolling boil and there is 212F (I have a brewing buddy that does calibrations of... well I might not be able to go there, but this is what he told me to do for mine).

^Second! But yes, I've stuck it under my tongue as well...

This does not work to accurately calibrate because water boils at different temperatures based on altitude. It boils at 212* at sea level. If you are anywhere off the coast, it will boil at different temps. My boils never get higher than 209* in the chicago area (according to my thermometers).

You could also get a reliable calibration from your rectum, but it's a real pain in the azz!

One could calculate the boiling point of water at a given altitude provided they had the barometric pressure , or just refer to a handy dandy chart, no harm there!
