Decimal odds are a different way to display betting odds instead of the fractional odds we usually see in the UK. They are particularly popular with tote and betting exchanges and are expressed as a figure that represents the total winning return. For example, odds of 5 (or 5.0) is the same as 4/1 in fractional odds, i.e., a winning return of £5, including the £1 stake. The easiest way to work out deicmal odds is to use a fractional to decimal odds converter.
