How to convert odds

All six formats describe the same price: what you win for each unit you stake. Here is how each one works and how to turn it into decimal odds.

Decimal odds

The number is what you get back for each unit staked, stake included. At 1.85, a stake of 10 returns 18.50. To get decimal odds from any other format, work out the profit per unit and add 1.

Fractional odds

Profit over stake: 5/4 means you win 5 for every 4 you bet. Decimal odds are the fraction plus 1, so 5/4 is 1.25 + 1 = 2.25. Evens (1/1) is 2.00.

American odds

A plus number is the profit on a stake of 100: +150 wins 150, which is decimal 2.50. A minus number is the stake you need to win 100: −200 means staking 200 to win 100, which is decimal 1.50.

Hong Kong odds

The profit for each unit staked, without the stake: decimal odds minus 1. 0.85 is decimal 1.85.

Malay odds

Always between −1 and 1. A positive number works like Hong Kong odds: 0.85 is decimal 1.85. A negative number is what you stake to win 1: −0.80 means staking 0.80 to win 1, which is decimal 2.25.

Indonesian odds

Positive numbers are 1.00 or more and work like Hong Kong odds: 1.50 is decimal 2.50. Negative numbers are −1.00 or less and work like American odds divided by 100: −2.00 is decimal 1.50.

Implied probability

100 divided by the decimal odds: the chance the price implies. 1.85 implies 54%. Add up the implied probabilities of every outcome in a market and you get more than 100%; the extra is the bookmaker's margin.
