# A change in temp.

1. Jan 11, 2006

My professor said yesterday that a change in temperature of 100 degrees Kelvin is equal to a chane of 100 degress Celcius, and finally this was equal to a change of 180 degrees farenhight. why is this correct given the equation F= 9/5C + 32 ?

That equation converts a specific temperature from one scale to another. What you want to compare are temperature changes: $\Delta F = 9/5 \Delta C$.
