Dave2 Wickham's Journal: Odd Degrees

I stumbled upon this page while looking for a decent source to cite to disprove someone who was claiming that Kelvin is measured in degrees. While looking there I saw that there are some...odd degrees. Degrees Twaddle? MacMichael? EBC? Lovibond?

dB

[subgeek]

i learned something about decibels i didn't know. i knew that if one sound is 10 dB louder than another, it will sound twice as loud. what i didn't know is that human perception is warped further, so that a signal that sounds twice as loud is really ten times as strong. makes sense of why two of something making the same sound aren't twice as loud as when just one is making the sound.

Degrees

...er, AIUI a the word "degree" technically does not refer to a fixed or defined unit of temperature, unless you say what scale you mean -- thus we say "degrees Fahrenheit", "degrees Celsius" and "degrees Kelvin". One degree Kelvin is also the same size as one degree Celsius; the only difference between Kelvin and Celsius is that 0K is absolute zero, which in Celsius is -273C (thus 273K and 0C are the melting point of water).

In America "degrees" is understood to mean F, but elsewhere "degrees" is understo

I was refering to the fact that you have degrees C and F, but not degrees K:

degree Kelvin (K)

an obsolete name for the kelvin. In the International System, temperatures on the absolute temperature scale are stated in kelvins, not in degrees Kelvin.
