Let’s look at how you can convert fractional odds to American odds.
Understanding American Odds
Fractional odds are commonly used in the UK and Ireland and represent the profit relative to the stake. American odds, on the other hand, are popular in the US and come in two forms: positive and negative. Positive American odds show how much profit you would make on a $100 stake, while negative American odds tell you how much you need to stake to make a $100 profit.
How to Convert Fractional Odds to American?
Formula:
The method of converting fractional odds to American odds depends on whether the fractional odds are greater or less than 1.
- For Fractional Odds Greater Than 1 (e.g., 5/1): American Odds = 100 * Fractional Odds, or 100 * (numerator / denominator)
- For Fractional Odds Less Than 1 (e.g., 1/5): American Odds = -100/(Fractional Odds), or (-100 / 1)/(numerator / denominator)
Step-by-Step Conversion from Fractional Odds to American
Converting Odds Greater Than 1:
- Fractional Odds: 5/2
- American Odds: 100 * (5/2) = 500 / 2 = +250
Converting Odds Less Than 1:
- Fractional Odds: 2/5
- American Odds: (-100 / 1) / (2 / 5) = -250
