Base 63 to Base 50

Base 63

In base 63, each digit position represents a power of 63: the rightmost digit counts individual ones, the next counts groups of 63, the next counts groups of 63×63, and so on — the same place-value idea as base 10, just with 63 distinct digits instead of ten.

Base 50

Base 50 works the same way: the rightmost digit counts ones, the next counts groups of 50, the next counts groups of 50×50, and so on, using 50 distinct digits.
