Tha number is about that number, for the purposes of my illustration it is a bit irrelevant. I also put a ? after the number to show I was guessing a bit.
To be precise
The Kelvin temperature scale (K) was developed by Lord Kelvin in the mid 1800s. The zero point on this scale is base on the point at which the pressure of all dilute gases mathematically project to zero from the triple point of water (see graph at left). Recall that the triple point is the temperature at which liquid water, ice, and water vapor can coexist simultaneously.
The zero point of this scale is equivalent to -273.16 �C on the Celsius scale. This zero point is considered the lowest possible temperature of anything in the universe. Therefore, the Kelvin scale is also known as the "absolute temperature scale". At the freezing point of water, the temperature of the Kelvin scale reads 273 K. At the boiling point of water, it reads 373 K.
I hope this answers all outstanding questions.

John, sir:
This is defined as the Kelvin system which has zero as absolute zero and water melting at 273.45 (?) and boiling at 373.45 K.Has this value changed recently? It was *water melting at 273.16 K and boiling at 373.16 K*. When was it re-fixed, I seem to be out of date, here.
Thanks,

There are two components to an answer to this question.
Yes if you are comparing the difference between two temperatures then 1 degree c is the same as 1.8 degrees f.
The base definition for the temperatures uses the triple point of water and the boiling point. However the starting point on the graph is different or in math the y intercept for the defining equation is different for the two systems.
In f it is 32 degrees F is the melting point of water
In c it is 0 degrees
But if we look at absolute temperature (ie absolute zero means there is no available heat energy in the system (without busting the atoms apart). Absolute zero is about -273 degrees C. This is defined as the Kelvin system which has zero as absolute zero and water melting at 273.45 (?) and boiling at 373.45 K.
So a strict answer is yes. If you are interested in the transformation of absolute temperature between scales then the offset point at 0 Kelvin is critical and one has a linear transformation to arrive at the answer and not a simple multiplication. But if you are comparing the difference between 10 and 20 C it is 10 degrees C, 10 degrees Kelvin and 18 degrees F
Clear as boiling mud.

Hello i have a question. Is 1 degree c equal to 1.8 degreesf? If this is true shouldn't 100 degrees c be equal to 180 degrees f. The reason i ask this is because isn't 10 degrees c equal to 18 degrees f? Thanks a lot for your help. h
