> It only takes a little electricity to power this process, which can raise the refrigerant’s temperature by many degrees Celsius.

And the same electricity can raise the temperature by even more degrees Fahrenheit!

Heat in F chill in C, et voilà! free energy.

Unit arbitrage. I love it.

I'd buy that for a dollar!

Using a temperature system built around water to measure air temperature. I mean I can use it but the range of fahrenheit is more useful.

What we really need is a combination of the two. Something that measures air temperature and water content because 68F at 5% humidity is a lot different than the same temp at 40%>

> Several accounts of how he originally defined his scale exist, but the original paper suggests the lower defining point, 0 °F, was established as the freezing temperature of a solution of brine made from a mixture of water, ice, and ammonium chloride (a salt). The other limit established was his best estimate of the average human body temperature, originally set at 90 °F, then 96 °F (about 2.6 °F less than the modern value due to a later redefinition of the scale).

Nothing beats scientific accuracy and thoroughness, right? So it then actually ended up being tied to water as well:

> For much of the 20th century, the Fahrenheit scale was defined by two fixed points with a 180 °F separation: the temperature at which pure water freezes was defined as 32 °F and the boiling point of water was defined to be 212 °F

The "feels like" apparent temperature accounts for things like humidity and windchill[1].

Many weather apps provide the "feels like" temp, including my app: https://uw.leftium.com

I was going to drop the "feels like" reading in my new weather app (I just didn't notice a major difference), but maybe I'll keep it...

Wet bulb temperatures account for evaporation, but I don't know if weather stations report wet bulb or dry bulb.
