Fraction and decimal odds – what is the difference?

June 28, 2009 by  

The traditional format is the fraction, e.g. ½. This is the format mos UK bookies keep by default. Other companies such as betfair use de decimal format, e.g. 1.7, 3.2

Our calculator will do this for you. However, if you want to calculate it yourself, the way to go from fractional odds into decimal is to divide and add one, e.g., 5/1+1=6.o or 3/2+1=1.5+1= 2.5. The firs fractional odds of 5/1 becomes decimal odds of 6, and the odds of 3/2 becomes 2.5.
