Betting Odds Converter FAQ
What is implied probability?
The chance the price asserts: 6/4 implies 40%. Sum a market’s implied probabilities and you get over 100% — the excess IS the bookmaker’s margin, visible once you convert. That literacy is this tool’s whole point.
Does this help me win?
No — it helps you READ. Conversion is arithmetic; outcomes are chance plus margins that favour the house by construction. Nothing here is gambling advice, and no converter changes the odds.
