Odds Converter; Decimal to Fractional. Remove 1 from the decimal and convert to a fraction, then reduce to simplest form: (decimal-1) - convert to fraction. Examples: 1.75: 1.75 – 1 =.75 = 75/100 = 3/4 2.20: 2.20 – 1 = 1.20 = 120/100 = 6/5. Decimal to American. To convert a decimal of 2.00 or higher: moneyline = (decimal – 1).100. The simple formular to convert from fraction odds to decimal is to divide the numerator (top number) by the denominator (bottom number) and add 1. The 1 represents the returned stake which is included in the decimal odds but not in the fraction odds. Example 1: Odds of 2/1, will be 2 divided by 1, which gives 2, then add 1 equals 3.

Implied probability is basically the conversion of odds into a percentage. That percentage then shows the likelihood of an outcome happening based on the size of the odds. High odds suggest a low probability of something happening, while low odds suggest a high probability of something happening.

Using this converter is easy. Simply enter the fractional odds into the box that states Fractional Odds. Fractional odds look like 2-1 0r 13/5. Press convert and the decimal odds will be shown in the Decimal Odds. This would be 3.00 in decimal odds, and 2/1 in fractional odds. The implied probability for these odds is 33.33%. In this example, the odds suggest that the player has a 33.33% chance of winning the match. This doesn’t mean that this is the player’s EXACT chance of winning the game.

For example, imagine a tennis player is +200 to win an upcoming match. This would be 3.00 in decimal odds, and 2/1 in fractional odds. The implied probability for these odds is 33.33%. In this example, the odds suggest that the player has a 33.33% chance of winning the match.

In sports, the probability of something happening is usually subjective. There are several factors to take into account and there’s always a chance of the unexpected. No one can state definitively the exact probability of a player or team winning a game they’re taking part in. There’s an element of personal opinion involved.

Calculating the implied probability is useful though. It helps us decide whether or not we think a bet offers any positive value. We should always look for positive value when betting, and it exists when our estimated probability of an outcome happening is greater than the implied probability that the odds on that outcome suggest.

Confused? Don’t worry! It’s not as complicated as it may seem. To make this easier to understand, let’s continue with the example of the tennis player at +200 to win his match. As we’ve said, the implied probability here is 33.33%. So if we think that the player has a GREATER than 33.33% of winning, then it makes perfect sense to bet on him. If we think his chances are less than 33.33%, it’s wise not to bet on him.

There are three main odds formats available to bettors; Fractional odds, Decimal odds and American odds. Fractional odds have historically beenused in the UK but Decimal odds are arguably the most popular format. How do you convert Fractional odds into Decimal or American? Read on to find out.

It might be obvious to most bettors but regardless of which odds format you use for a bet, the potential profit will always be the same - it is just how these odds are presented that differs.

Fractional odds, unsurprisingly, are displayed as fractions. American odds use a unique + and - system and Decimal odds, as you may have guessed, are displayed as decimals - the key difference is that Decimal odds always include the stake.

You can use our helpful bet calculator to work out the potential profit and return of your bet in any odds format, but knowing how to work this out for yourself is a critical part of understanding how odds work and ultimately, being able to calculate expected value.

Fractional odds to Decimal odds conversion

Converting Fractional odds into Decimal odds is fairly straightforward. Simply turn the fractional number into a decimal number by turning the fraction into its decimal equivalent and then, crucially, add one.

Here’s an example of how to convert Fractional odds into Decimal odds:

5/2 = 5/2 + 1 = 3.5

If you are more comfortable with Fractional odds you can convert Decimal odds by reversing the formula above:

Decimal odds -1 and converted into a fraction = Fractional odds

3.5 – 1 = 2.5 which as a mixed fraction is 21/2 but in its more common improper form is 5/2.

Calculating profits with Fractional odds

Fractional odds originated within horse racing as a way to represent the return on the underlying probability. They shouldn‘t be confused with ratios. Although 3/1 or “three to one” make it easy for bettors to understand their profit in relation to the stake – your return is three times your stake - the more accurate and precise the odds are, the more complicated things become.

Odds expression (most commonly used in the UK) which presents odds in a fractional format.

The easiest way to calculate profits using Fractional odds is to view the fraction as Profit/Stake - so a $1 bet at 5/1 would result in $5 profit. However, the odds can be unfamiliar fractions (proper and improper) and your stake might not always be a whole number so the following equation should be used:

Returns = (Stake / denominator) x numerator) + stake

So if we use a $15 bet at odds of 5/2, the calculation would be as follows:

Calculating profits with Decimal odds

Decimal odds have become increasingly popular in recent years. Bettors are beginning to favour the simple, more accurate Decimal representation of a bet’s potential return, which includes the stake amount.
