Converting Decimal Odds
Decimal odds are the modern standard in the world of online betting, but you may occasionally encounter fractional odds and so it is worth knowing how to convert such fractions into the decimal odds that you are now familiar with. In this article we will explain how to do just that with ease. All you will need is your pocket calculator (or a calculator application open on your computer screen) and the step-by-step instructions that follow in a moment.
Understanding what fractional odds such as 6/4, 2/1 and 10/3 represent makes the conversion process easy to understand. The left hand side of the odds tell you how many units of profit a bet will make is you stake the number of units on the right hand side. 6/4 therefore means that if you stake £4, you would make a profit of £6 for a total return of £10.
Decimal odds also tell us how much profit we will make from a bet, but as you will remember our decimal odds figures include our returned stake. This means that to convert fractional odds to decimal odds we need to take the left hand side of the fraction (we'll call this L), divide by the right hand side of the fraction (we'll call this R) and then add 1 to incorporate the returned stake. This could be summarised as:
( L / R ) + 1
Taking odds of 6/4 as an example, our conversion to decimal odds here would require us to take 6, divide by 4 and then add 1:
( 6 / 4 ) + 1
( 1.50 ) + 1 = 2.50
Odds-on fractional odds are converted in exactly the same way, so if you come across fractional odds such a 1/3, the calculation would be:
( 1 / 3 ) + 1
( 0.33 ) + 1 = 1.33
Decimal Odds Conversion Table
Although converting fractional odds to decimal odds is easy, many people like to have a decimal odds conversion table on hand to help them convert odds even when they don't have a calculator available. If this idea appeals to you then the decimal odds conversion table below is one that will help you to convert fractional odds from 1/5 to 9/1. For fractional odds of 10/1 and higher (and all fractions that just have 1 as the right hand side figure, come to that) you should be able to carry out the calculation in your head quite easily.
