Calculator: Converting Moneyline Odds into Win Probability

Here's a neat little rig that helps you with your handicapping by helping you, at a glance, figure out whether or not you've got an edge. See the instructions below. NOTE: This converter does not take into effect the juice (vig), but instead handles it as if this were a perfect world. Also, it can only handle actual percentages, so don't try to stick ".645" in there. Instead, type in "64.5". Enjoy!
