Odds to Implied Probability автор Danny Hines

Odds Converter translates American betting odds—such as +140 or -110—into easy-to-understand implied probabilities. Instead of mentally decoding unfamiliar odds, you can immediately see the percentage the price represents.

For example, +140 implies a break-even probability of approximately 41.7%. If you believe the outcome has a greater than 41.7% chance of happening, the bet may be worth considering. This creates a probability-first experience similar to prediction markets, where prices communicate how likely an outcome is considered to be.

The extension can preserve the original odds, append the implied probability, or display only the percentage. It also watches for live page updates, automatically recalculating probabilities when sportsbooks change their odds.

Displayed probabilities include the sportsbook’s margin and are not predictions, guarantees, or betting advice.
