1. What is Odds to Percentage Conversion?

The odds to percentage conversion calculates the implied probability of an event occurring based on given odds. It transforms decimal odds into a percentage probability that helps assess the likelihood of an outcome.

2. How Does the Calculator Work?

The calculator uses the following formula:

\[ \text{Percentage} = \frac{1}{\text{Odds} + 1} \times 100 \]

Where:

Explanation: The formula converts decimal odds to their implied probability percentage. Lower percentages indicate less likely outcomes, while higher percentages indicate more likely outcomes.

3. Importance of Odds Conversion

Details: Converting odds to percentages helps bettors and analysts understand the true probability implied by the odds, allowing for better decision-making and value assessment.
