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%>
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
For some reason I never noticed there are exactly 180 degrees between freezing and boiling points on the Fahrenheit scale. 100°C is a nice "round" number, and 180°F divides evenly into a lot of smaller numbers.
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...
