Is 2 degrees fahrenheit twice as hot as 1 degree fahrenheit?

Not the least bit.

Something at 2 degrees has a little bit more energy in it.

Or better yet, is 2 degrees Kelvin twice as hot as one degree Kelvin?

Or better yet, is 2 degrees Kelvin twice as hot as one degree Kelvin?

Same as the first answer, isn't it?

Or better yet, is 2 degrees Kelvin twice as hot as one degree Kelvin?

Why yes, yes it is.

I think in the case of Kelvin it might be, since 0K is the lowest possible temperature (not counting quantum effects)

Is 2 degrees fahrenheit twice as hot as 1 degree fahrenheit?

no it isn't.

Fahrenheit doesn't as it's a relative scale, whereas kelvin is an absolute so it does.

No, but -457.67 degrees Fahrenheit is twice as hot as -458.67 degrees Fahrenheit...

But which feels colder, -40 degrees celsius or -40 degrees fahrenheit?

Neither feels as cold as 243 Kelvins.

-40 is a lot less than 0 degrees.

-40 is a lot less than 0 degrees.

Depending on the scale used. Although 233 kelvins is equal to -40 C. So looks like we were both wrong, lousy math skills . . .

Not really. Well, you can't define "twice as hot" in any sensible terms. At least not unless you're using the absolute Kelvin scale, and even that is quite a stretch.

You can calculate the kinetic temperature of matter as 3/2 * kB * T, where T is the temperature and kB is the Boltzmann constant. 1 Farenheit is 256 Kelvin and 2 F is just the slightest bit more, 256.5 Kelvin. So the kinetic temperature would barely change at 2F compared to 1F.

I tried searching for the Furry Freak Brothers comic where Fat Freddy gets lost inside his freezer. In that episode he says "It's freezing in here, it must be 40 below! I wonder what that is in Celsius?" and the editor says "They are the same!". But no joy

Is 2 degrees fahrenheit twice as hot as 1 degree fahrenheit?

no, one temperature is only double another when they are both in the kelvin scale (40 F is not double 20 F, but 300 K is double 150 K)

In the formulas below, / represents division, * represents multiplication, - subtraction, + addition and = is equal.

Tc = (5/9)*(Tf-32); Tc = temperature in degrees Celsius, Tf = temperature in degrees Fahrenheit

For example, suppose you have a Fahrenheit temperature of 98.6 degrees and you wanted to convert it into degrees on the Celsius scale. Using the above formula, you would first subtract 32 from the Fahrenheit temperature and get 66.6 as a result. Then you multiply 66.6 by five-ninths and get the converted value of 37 degrees Celsius.

Below is the formula to convert a Celsius scale temperature into degrees on the Fahrenheit scale.

Tf = (9/5)*Tc+32; Tc = temperature in degrees Celsius, Tf = temperature in degrees Fahrenheit

Assume that you have a Celsius scale temperature of 100 degrees and you wish to convert it into degrees on the Fahrenheit scale. Using the stated formula, you first multiply the Celsius scale temperature reading by nine-fifths and get a result of 180. Then add 32 to 180 and get the final converted result of 212 degrees on the Fahrenheit scale.

ps. Temperature is not a logarithmic scale; it is linear.

EDIT: Oops, didn't mean to bump this silliness.

But which feels colder, -40 degrees celsius or -40 degrees fahrenheit?

I guess we'd have to ask the Canadians and the Alaskans. I'm sure they'll both say that "-40 is not really all that cold"
