If you are following a UK tipster or betting on a European horse race, you will likely see odds like 4/1, evens, or 1/2. To a US bettor, these don’t immediately reveal the risk required or the profit potential in the familiar $100-based Moneyline format.
Our Fractional to American Converter allows you to quickly see that 4/1 is +400 and 1/2 is -200, making it easy to place your bets on US sportsbooks with confidence.
How to Use the Calculator
The converter translates the ratio of profit/stake into the American plus/minus system:
- Enter Fractional Odds: Type the fraction (e.g., 5/2) or use a single number for whole-number odds (e.g., 5 for 5/1).
- Get American Odds: The tool identifies if the bet is an underdog or a favorite (e.g., 5/2 becomes +250).
- Understand the Sign:
- Plus (+) means the profit is greater than the stake (Underdog).
- Minus (-) means the stake is greater than the profit (Favorite).
Conversion Examples
- Odds Against (e.g., 2/1): The first number is larger. This converts to positive American odds. 2/1 becomes +200.
- Odds On (e.g., 1/2): The second number is larger. This converts to negative American odds. 1/2 becomes -200.
Frequently Asked Questions (FAQ)
What is “Evens” in American odds?
In fractional format, “Evens” is 1/1. In American odds, this is +100. It means your profit equals your stake.
How do I convert 10/11 manually?
Divide the denominator by the numerator and multiply by -100. (11 ÷ 10) * -100 = -110. This is the standard “juice” price for US spreads.
Which is easier to use: Fractions or American?
It is a matter of preference. Fractions are great for understanding simple ratios (4/1 is “four times your money”). American odds are designed to show exactly what a $100 bet earns or requires. For complex calculations like parlays, most pros convert both to Decimal format.
