What are these odds formats? How do they translate? Find out more in the following paragraphs.

American odds are the third major odds format in online sports betting today. It is mostly used in North America, and mainly in the USA.

American odds are expressed in numerical format, and can be negative (e.g. -200) or positive (e.g. +100).

When the number is positive, it expresses the amount that can be won for a $100 bet. If the odds are +100, for example, $100 can be won for a bet of $100 (equivalent to decimal odds of 2.00 in Europe).

When the number is negative, it expresses the amount you need to bet to hope to win $100. For example, if the American odds are -200, this means that you need to bet $200 to win $100 (equivalent to odds of 1.50 in Europe).

To calculate the potential profit of a bet based on positive American odds (i.e., by removing the stake), first divide the stake by 100, then multiply the result by the odds.

As for calculating potential profit with negative American odds, first divide 100 by the American odds (without taking out the "-"), then multiply the result by the stake.

For a bet of $10 on **positive American odds** of +100, here's the profit that can be obtained:

- 10 (stake) / 100 = 0.1; then 0.1 x 100.00 (odds) = 10 (potential profit)

By betting $10 on American odds of +100.00, I can expect to make a profit of $10 (equivalent to European odds of 2.00).

Another example with **negative American odds**: for a bet of $10 on American odds of -200, here's what you get:

- 100 / 200 (odds) = 0.5; then 0.5 x 10 (bet) = 5 (potential profit)

For a bet of $10 on American odds of -200, you can expect to make a profit of $5, which is equivalent to a bet of $10 on European odds of 1.50.

Don't want to waste your time with these calculations, let alone make a mistake? Then use our odds converter without further ado, which also delivers the potential winnings of a bet in record time. Including the expected net profit!

Decimal odds are unquestionably the most widely used in Europe. If you've ever visited a sports betting site, you're bound to be familiar with it.

Decimal odds are expressed in numerical format with commas, ranging from 1.01 to odds as high as 5000.00.

The smaller the odds, closer to 1.00, the greater the chance of a winning bet. Conversely, the further away from 1.00 the odds are, the less likely the bet is to win.

To find out the potential payout of a bet using decimal odds, simply multiply them by the stake involved.

For a bet of $10 on odds of 1.80, here's how much you could win:

- 10 (stake) x 1.80 (odds) = 18 (potential gross win)

In the event of a winning bet on odds of 1.80 with a stake of $10, the bettor can therefore expect to win a gross profit of $18.

Clearly, the further away from 1.00 the decimal odds are, the greater the potential winnings. Imagine odds of 5.00: 10 (stake) x 5.00 (odds) = $50 in possible winnings!

Fractional odds, also known as fractional odds or English odds, are an odds format mainly used in the UK.

As the name suggests, fractional odds are expressed as a fraction, with the potential win of the bet in the numerator (top number), and the stake in the denominator (bottom number).

For example, odds of 1/1 mean that for every $1 wagered, $1 of profit will be made. Similarly, odds of 2/1 mean that for $1 wagered, the profit will be $2 in the event of a winning bet.

The greater the numerator of fractional odds, the greater the potential profit of the bet.

To determine the potential profit of a bet based on fractional odds, simply multiply the numerator by the stake.

With fractional odds, you skip the winnings stage and immediately determine the profit (see the difference here).

Importantly, when the numerator (top number) is smaller than the denominator (bottom number), this means that the initial bet is higher than the potential payout (equivalent to decimal odds below 2.00). The calculation is then different (see below).

**When the numerator is greater than or equal to the denominator**: for a bet of $10 on fractional odds of 1/1, here's what you get:

- 10 (bet) x 1 (numerator of the fraction) = 10 (potential profit).

If you bet $10 on odds of 1/1, you can expect to win $10 on a winning bet.

**When the numerator is less than the denominator**: for a bet of $10 on fractional odds of 4/5 now, here's what you can get:

- 10 (stake) / 5 (denominator) = 2; then 2 x 4 (numerator) = 8 (potential profit)

We can therefore expect to win $8 net with a $10 bet on odds of 4/5

When the top number of the fraction is smaller than the bottom number, first divide the stake by the denominator (bottom number), then multiply the result by the stake.

Converting decimal odds into American odds requires a little calculation.

If the decimal value you wish to convert is greater than or equal to 2.00, you need to subtract one unit (1) from it, then multiply it by 100.

For example, for a decimal value of 2.20: 2.20 - 1 = 1.20; then 1.20 x 100 = 120.

Decimal odds of 2.20 therefore corresponds to American odds of +120.

If you want to convert decimal odds below 2.00 to American odds, you need to take the odds and subtract one unit (1). Then divide 100 by the result obtained and add a "-" sign in front of the value.

For example, for decimal odds of 1.50: 1.50 - 1 = 0.5; then 100 / 0.5 = 200. So -200.

A decimal value of 1.50 is therefore expressed as -200 in American format. To save you the trouble, our automatic odds converter is available 7 days a week, 24 hours a day.

To manually convert American odds into decimal odds, the calculation again depends on the value of the U.S. odds. Whether it is negative or positive, the calculation is not the same.

To convert positive American odds into decimal odds, divide the American odds by 100, then add this result to 1.

For example, for American odds of +400: 400 / 100 = 4; then 4 + 1 = 5.

American odds of +400 are therefore expressed as 5.00 in decimal format.

To convert a negative American odds into a decimal, you need to divide 100 by the negative American odds, then subtract this result from 1. It's a complicated calculation!

For example, for American odds of -200: 100 / (-200) = -0.50; 1 - (-0.50) = 1.50.

American odds of -200 are thus expressed as 1.50 in decimal format.

As these calculation methods are rather difficult between decimal odds and American odds, we can only advise you to use our tool. You'll save precious time.

To convert fractional odds (also known as English odds) into American odds, you can use the following calculations.

To convert a positive fractional value, i.e. one with a numerator greater than or equal to the denominator (e.g. 1/1; 3/1; 10/1), you need to divide the fraction, then multiply the result by 100.

For example, for odds of 4/1: 4 / 1 = 4; then 4 x 100 = 400.

Fractional odds of 4/1 are therefore expressed as +400 in American odds format.

To convert negative fractional odds (numerator less than denominator) into American odds, you need to produce the faction division, and divide -100 by this result.

For example, for odds of 1/2: 1 / 2 = 0.50; then (-100) / 0.50 = -200.

A fractional odds of 1/2 is thus expressed as -200 in American format.

To convert American odds into fractional odds, there are two calculations. One calculation is to be used for positive American (e.g. +200), and another calculation is to be used for negative American odds (e.g. -200).

To convert positive American odds into fractional odds, divide it by 100 and then express it in fractional format (the value with a denominator of 1).

For example, for American odds of +200: 200 / 100 = 2; then 2 = 2/1.

American odds of +200 are therefore translated as 2/1 in fractional format.

To convert negative American odds into fractional odds, divide -100 by the odds, then remove the negative signs per equation, and do the same for the two "0 "s in the hundreds.

For example, for American odds of -500: (-100) / (-500) = 100 / 500 = 1/5.

American odds of -500 are thus expressed as 1/5 in fractional odds.

To convert decimal odds into fractional odds, you can proceed without our tool using a calculation. But be warned: it's not always easy, and it can be time-consuming!

To proceed, you need to take the decimal value, subtract one unit (1) and express it as a fraction. In the case of 2.00: 2 - 1 = 1/1.

A decimal value of 2.00 is thus expressed as 1/1 in fractional value.

To convert a fractional quotation into a decimal quotation without using our tool, add a unit (1) to the numerator of the fraction (top number), and delete the denominator.

For example, for fractional odds of 5/1: 5 + 1 = 6.

Fractional odds of 5/1 are expressed as 6.00 decimal. Once again, the easiest way is to use our automatic odds converter!

Thanks to our sportsbook odds conversion tool, you can not only convert every value offered by an online betting site, but also determine in a second the potential win and profit of your bet.

But what's the difference between a bet's profit and its loss? It's quite simple, really.

The winnings on a bet are actually the gross winnings, what the sportsbook pays out to us in the event of success. For example, for a bet of $10 on odds of 2.00, the payout will be $20.

Profit, on the other hand, is the winnings from the bet minus the initial stake. In other words, it's the net win of the bet, and the money that's actually won in the event of a winning bet.

For a bet of $10 on odds of 2.00, for example, the profit will be $10, since the original stake is deducted, which is in no way a win (you're just getting your money back).

So, when you place sports bets, focus on the profit, not the win. That's how you build up a solid bankroll over the long term.

Within our odds converter, you'll find a field called Implied probability. This field is for information only, and shows you the probability of a bet winning according to the sportsbook's estimate.

For example, if you enter decimal odds of 2.00 on the tool, you'll see that the implied probability of the bet winning is 50%, according to the sportsbook.

How is this useful? Quite simply, by helping you decide whether or not to place a bet!

If you personally feel that your bet has a better chance of going through than the sportsbook thinks, don't hesitate to give it a try. The sports betting site may have missed an important piece of information about the sporting event, such as an injury or suspension.

On the other hand, do you think your bet has less chance of being validated than the sportsbook thinks? In that case, the odds are too low in your opinion, and the risk involved in your bet is probably not worth the potential gain.

This field is therefore extremely interesting, as it lets you know at a glance whether a bet is really worth taking or not. Pretty handy!
