I don't know how Fahrenheit is defined! I guess that's sad.

I just know what a 40 degree day feels like, or a 72 degree day, or a 108 degree day…

From a standpoint of reason, of course I understand metric makes much more sense. I think it should be adopted, I think it should be used in science, etc. For many units, like length/distance, volume, weight, etc., I'm able to "think" in metric, but for whatever reason, when I see km/h I have to do a quick calc in my head (divide by 1.6 or so) and when I see degrees C I have to multiply by 1.8 and add 32 — I blame my parents!

I wouldn't argue that non-metric is better, I'm just acknowledging I have a ways to go for some measurements, while some people I know don't have much of a clue at all about metric equivalents. Maybe NEXT generation…

So, Kevin, to me it's quite different: not only do i have no feeling of what fahrenheit "feels like", i would have to look it up to be able to do the conversion.

(How) Are °F defined anyway? Wikipedia(en) cites at least five different ones.

BTW, people – Astronomy uses metric. Thanks for using the “US” imperial measures, though. It’s what I use..

It may be the longest holdout in the switch to a metric system. I thought the weather report was nice, so I dropped the link to this post in an email for a couple of friends and family — with no conversion needed since the temps were already in F.

Old habits die hard. I'm pretty good (at thinking Metric) in units of distance, volume, and weight, but still like to have my velocity/time (km/h) converted to mph when discussing ground-based speed and my temperature converted to F when discussing temperatures that relate to weather conditions (and HP and ft-lbs of Torque may never go away…).

I don't think you can argue the efficacy of F vs. C, just the depth to which F is ingrained while C still feels unfamiliar. Conversions are good, either way.

32°F is the freezing point of water and 212 °F the boiling point??? (180 points between…That makes plenty of sense! Seems pretty arbitrary and harder to calculate with?)

Anyway, I would also like to see Metric measurements if possible please… eventually we will all be using them.

Fahrenheit is a standard, and is in many ways a better gauge for climate temperature:

A notable feature of the Fahrenheit scale is that the broader range of temperatures experienced in a temperate climate span the scale generally from 0 to 100 degrees, whereas this range of temperatures would span the Celsius scale within the relatively small numerical range of -17 to 37 degrees. This results in decades, or ranges of 10 degrees of the Fahrenheit scale, being able to be used to describe the feel of a day's temperature, i.e. "the 60's" would indicate that the temperature falls in the distinctive range of 60° – 69° F. Stating such a range in Celsius could be considered to be a bit more awkward, as rather than saying "in the 60's", one would have to say something along the lines of "between 15 and 20".

What do you base that on? Microbes grow in much harsher environments on Earth.

Too many armchair scientist here.

I understand the need for imperial for the US audience as this is a popular science website, but Metric conversions would be a nice inclusion as standard…

-22ºF = -30ºC
-112ºF = -80ºC

Just to set the record straight we in Canada use Celsius and I suspect NASA scientists are using Kelvin (same degrees, different 0 point i.e. -273 (and change) ºC). So a good Canadian weather station would be reporting in metric. The Fahrenheit is merely for the US public. Conversions were gratefully provided by Google.
