Can anyone tell me the equivalency between Indian Classical Saptak, i.e. Sa Re Ga Ma Pa Dha Ni Sa and Western Notes, C D E F G A B

It is Sa ~ C, Re ~ D, Ga ~ E, etc, or is it something else.

Please let me know

Reason I'm asking is, I'd love to be able to play https://noobnotes.net/do-re-mi-sound-of-music/ on Bansuri

Already this video sounds quite similar to Do a Deer A Female Deer
