If you are a fan of sports betting, you may have come across different types of odds formats. One of the most common ones is fractional odds, which are used mainly in the UK and Ireland. Fractional odds show the ratio of your potential profit to your stake, such as 2/1 or 11/4. However, some bettors may prefer to use decimal odds, which are more popular in Australia and Europe. Decimal odds show the total return you will get for every unit you stake, such as 3.00 or 3.75.

But how do you convert fractional odds to decimal odds, or vice versa? You may need to do this if you want to compare different betting options or use a different odds format than the one offered by your bookmaker. Luckily, there is a simple way to do this using a calculator or a formula.

To convert fractional odds to decimal odds, you need to divide the numerator (the first number) by the denominator (the second number) and then add 1. For example, if the fractional odds are 2/1, you need to divide 2 by 1 and then add 1, which gives you 3.00 as the decimal odds. Similarly, if the fractional odds are 11/4, you need to divide 11 by 4 and then add 1, which gives you 3.75 as the decimal odds.

To convert decimal odds to fractional odds, you need to subtract 1 from the decimal and then convert it to a fraction. For example, if the decimal odds are 3.00, you need to subtract 1 from 3 and then convert it to a fraction, which gives you 2/1 as the fractional odds. Similarly, if the decimal odds are 3.75, you need to subtract 1 from 3.75 and then convert it to a fraction, which gives you 11/4 as the fractional odds.

If you don’t want to do the math yourself, you can use our handy Decimal to Fractional Odds Converter tool on this page. Just enter any decimal or fractional odds value and click on “Convert” to see the equivalent value in the other format. You can also see the implied probability of each outcome based on the odds.

Frequently Asked Questions About Our Tool

Q: What is implied probability?
A: Implied probability is the percentage chance of an outcome occurring based on the odds. It can help you assess how likely a bet is to win or lose. To calculate implied probability from fractional odds, you need to divide the denominator by the sum of the numerator and denominator and then multiply by 100. For example, if the fractional odds are 2/1, you need to divide 1 by (2+1) and then multiply by 100, which gives you 33.33% as the implied probability. To calculate implied probability from decimal odds, you need to divide 1 by the decimal and then multiply by 100. For example, if the decimal odds are 3.00, you need to divide 1 by 3 and then multiply by 100, which gives you 33.33% as the implied probability.

Q: Why should I use decimal or fractional odds?
A: The choice of using decimal or fractional odds depends on your personal preference and convenience. Some bettors may find decimal odds easier to understand and compare because they show the total return for each unit staked. Others may prefer fractional odds because they show the potential profit relative to the stake and are more traditional in some markets. You can use our Decimal to Fractional Odds Converter tool to switch between different formats whenever you want.

Q: Are there any other types of odds formats?
A: Yes, there are other types of odds formats besides decimal and fractional. One of them is American or moneyline odds, which are popular in North America. American odds show how much you need to bet or win for every $100 staked or won. They can be positive or negative depending on whether the outcome is favored or not. For example, American odds of +200 mean that you will win $200 for every $100 staked.
