Odds range from 0 to infinity, while probabilities range from 0 to 1, and hence are often represented as a percentage between 0% and 100%: reversing the ratio switches odds for with odds against, and similarly probability of success with probability of failure.

What is an odds converter?
Odds can be displayed in many different ways, including as fractions, decimals and if you're in the USA, with a positive or negative sign. Therefore, an odds converter allows you to quickly convert US Odds (such as +100) to UK odds (such as 1:1) to Australian Odds (such as $2.00). It's important to realise that although they all look different they are all just indicating the same price of an event with numbers.
An odds converter is especially beneficial if you have moved to a new country with a new odds format, if you are travelling or if you are betting with an international sportsbook.
Decimal odds show the amount of money the bettor will receive back multiplied by the original stake. For example, if the price is $7.50, and the bet is successful, the bettor will receive 7.5 times their original stake.
Fractional odds are stating the same thing, in a different format. In fractional odds, whatever the second number is, can be seen as the stake, and whatever the first number is, is what the bettor will receive back should the bet be successful. For example, if the price is 15/2, the bettor will receive 15 'stakes' for every 2 they wager.

American odds are slightly different and are based of stakes off a $100 bet. When the odds are with a + sign, they represent the amount of money you would receive back from a bet of $100. When the odds are displayed with a - sign, that represents the amount if money the bettor would have to wager to receive a $100 profit. For example, if the odds are +750, the bettor would receive $750 dollars if their bet was successful. If the odds were -750, the bettor would have to wager $750 in order to profit $100 (and therefore receive back $850 in total).
Now you can tell that $7.50, 13/2 and +650 all mean the same thing and the need for an odds converter!
