Looking for odds calculator for winning percentage

[mirinquads]

The old SBR had a calculator where you could input the odds and that would calculate the theoritical percentage of the play to win: I.e: -200 odds = a 35% chance to win the bet.

It seems to have been taken down, can any of you studs points me to a similar one? If not, a book that tells you how its calculated so I can make my own..

For some reason, I just cant find it anywhere.
