Base 32 to Base 58

Base 32

In base 32, each digit position represents a power of 32: the rightmost digit counts individual ones, the next counts groups of 32, the next counts groups of 32×32, and so on — the same place-value idea as base 10, just with 32 distinct digits instead of ten.

Base 58

Base 58 works the same way: the rightmost digit counts ones, the next counts groups of 58, the next counts groups of 58×58, and so on, using 58 distinct digits.
