Convert American odds to decimal odds and calculate the implied probability.

If you are a sports betting fan who wants to understand and compare American and Decimal odds formats, you have come to the right place. Odds are the way of expressing the likelihood of an event happening, and they can vary depending on how they are displayed. American and Decimal odds are two of the most common formats of odds in the world.

American odds are more prevalent in the US and Canada, and they show how much you need to bet to win $100 (if the odds are positive) or how much you will win for every $100 you bet (if the odds are negative). For example, if you bet $10 on an event with American odds of +150, you will win $15 ($10 x 150/100) plus your stake back, for a total return of $25. If you bet $10 on an event with American odds of -200, you will need to bet $20 ($10 x 200/100) to win $10 plus your stake back, for a total return of $30.

Decimal odds are the easiest and most common way to show odds. They indicate how much you will win for every unit you bet. For example, if you bet $10 on an event with decimal odds of 2.5, you will win $25 ($10 x 2.5) if your bet is successful.

**Q: How do I convert American odds to Decimal odds?**

A: To convert American odds to Decimal odds, you need to follow different rules depending on whether the American odds are positive or negative.
