How to convert betting odds
Decimal odds show total return per unit staked. American positive odds show profit on a 100-unit stake, while negative odds show the stake needed for a 100-unit profit. Fractional odds express net profit relative to stake. Implied probability is 100 divided by decimal odds.
Example: decimal odds of 2.50 equal American +150, fractional 3/2 and 40% implied probability.
