What are British and American odds in bookmaker?

Coefficient (keff) is a numerical form of displaying the probability of the outcome of a sports match, taking into account the subjective opinion of the bookmaker and its margin (bookmaker’s profitability). In domestic offices, the decimal (European) coefficient is most common, but there are also British (fractional) and American ones. Mightytips experts talk about the features, pros and cons of British and American quotes.

What do British and American odds mean?

British coefficient

As already mentioned, above, the second name of the British coefficient is fractional. It looks like this – 2/11, 3/10, etc.

How to calculate and translate the British odds into the decimal form 1.5, 1.85, etc., which is more usual for domestic bettors? Let’s take British odds 2/11 as an example. It is deciphered simply: to get a net profit of 2 rubles, you need to put 11 conventional units. The payment amount in case of success will be 13 rubles. This odds are relevant for an event with a high probability of passing.

Consider also an example of an unlikely event. For example, they give it a 3/1 odds. With a bet of 1000 rubles, the net winnings will be 3000, and the total payout is 4000 rubles.

Another case. You intend to bet 100 rubles at a 6/4 odds. How do you know how much you will win? We use the formula 6/4 x 100 = 150 rubles. This will be a net profit, and the total payment will reach 250 rubles.

Summing up, we can say that the fractional (British) coefficient looks like a classic fraction, the denominator of which is the number of monetary units that must be bet in order to win the amount from the numerator.

American odds

Even more unusual for bettors from the CIS is the American coefficient. No fractions are used here, but American odds can be positive and negative. It looks like +100 or -150.

The sign “-” is a sign of favoritism in American kefs. In principle, one can draw an analogy with decimal odds and a minus handicap for the favorite team.

Let’s look at a specific example. Let’s say you see odds of -350 for the favorite of the fight. This means that to get a net profit of 100 rubles, you need to put 350 rubles.

If you decide to bet on an outsider, then he will always be given a quote with a plus. Let’s say you see a rate of +800. It means that with a bet of 100 rubles, you will receive 800 rubles of profit.

We draw a conclusion. If there is a plus at the beginning of the odds, then the number following it corresponds to the net profit that you can get with a bet of 100 currency units. If there is a minus at the beginning, then the next number corresponds to the amount that needs to be bet to get a net profit of 100 units.

Converting British and American odds to decimal

To convert the British coefficient 22/5 into the European one, you need to divide the numerator 22 by the denominator 5 and add to the resulting value 1. We get: 22 รท 5 + 1 = 4.4 + 1 = 5.4, which is the European expression for the British coefficient 22 / 5.

The transformation of a more difficult-to-perceive American odds into a European one depends on whether it is a positive or negative quote. If the odds are with a plus sign, then we add 100 to its value and divide the amount by 100. For example, the American coefficient +1500 after conversion to decimal format will look like this:
(1500 + 100) / 100 = 1600/100 = 16.0.

If we see the American odds in front of us with a minus, then we take its value, add 100 and divide the amount by its value. In this case, we use in the calculations the value of the coefficient as a positive number. Let’s calculate the European coefficient for the American -350:

(350 + 100) / 350 = 450/350 = 1.28.

Not only domestic, but also most European offices often use European coefficients. Nevertheless, British and American quotes also have the right to life, so it is better for the bettor to familiarize himself with the rules for calculating them before starting bets.
