Question

We learned about the different levels of measurement. For example, temperatures in Fahrenheit have a level of interval because they can be put in order, differences have meaning, but ratios don’t make sense. If it is 20 degrees Fahrenheit on Monday and 40 degrees Fahrenheit on Tuesday, it would not make sense to say that it was (40/20=2) twice as hot Tuesday.

Is this also the case for Celsius?

How about Kelvin

Answer 1

yes, the case for celsius is same as that of Fahrenheit because location of zero is arbitrary for both celsius and Fahrenheit due to which both celsius and Fahrenheit are interval scale.

This can be explained by using the difference of 20 degree celsius which is always equal to 36 degree Fahrenheit. So, both celsius and Fahrenheit are interval scales

Kelvin is not interval and it has the meaning of ratio, i.e. we can say that it is twice as hot tuesday using the kelvin measurement because the location of zero is not arbitrary in the case of kelvin.

so, kelvin is different from Fahrenheit and celsius.
