I’m trying to convert an encrypted set of coordinates.

Given:

04 33.135

533 17.961

The numbers 04 3.15 in the first set are red.

The puzzle is supposedly based on PI, given as:

314159265358979

The first set of given numbers will (more than likely) start with 35 (instead of 04), the second set will probably start with 120 (instead of 533).

Any ideas?
