Understanding Odds Formats
Sports betting odds can be displayed in three different formats: American (moneyline), Decimal (European), and Fractional (UK). Our odds converter tool instantly converts between all three formats, helping you understand betting lines no matter which sportsbook you're using.
American odds use plus and minus signs (e.g., +150 or -200), decimal odds show your total return (e.g., 2.50), and fractional odds display profit as a fraction (e.g., 3/2). Understanding how to read and convert between these formats is essential for comparing odds across different sportsbooks and finding the best value.
