Kai:
Yes you have the direction....but it is not necessary to derive every value unless Raghu has desire for two things....
1) If he wants to eliminate the interpolation in the end application entirely and have a straight table lookup.
2) He wants to ensure that the FLASH space of his microcontroller is very full of a large table.

On the other hand he can select specific entries such as 50, 75, 100, 125.........375, 400, 425, 450, 500 and just tabularize the corresponding degrees values and perform linear interpolation between them at run time.
