 Fractional and decimal odds

# Fractional and decimal odds

The first thing you notice when you visit an online bookmaker is definitely odds format. If you're coming from the UK and are used to fractional odds format used at most UK bookmakers, odds displayed as 1.62 or -133 will definitely confuse you. Most of the online bookmakers will allow you to choose your preferable odds format, but in case you want to convert odds for any reason, you will need to understand how these things work.

UK based punters are used to fractional odds, but decimal odds format is pretty straightforward and quite simple - bigger number means bigger odds. And that's it.

The only thing you need to have in mind is that your stake is included in odds, which means that decimal odds of 2.00 are evens or 1/1, 3.00 are 2/1, etc.

## How do you convert from decimal to fractional odds?

1. Subtract 1.00 from decimal odds
2. Convert to a fractional number
3. Reduce fractional number to its simplest form

For example, if you have decimal odds of 1.50, the procedure will look something like this: Subtracting backer's stake from starting odds: 1.50-1.00 = 0.50

Converting 0.50 to a fractional number will give you 50/100, and when you reduce it by 50 you will get 1/2.
Or to cut the story short:

1.50 - 1.00 = 0.50 = 50/100 = 1/2

Few more exmaples:

1.75 - 1.00 = 0.75 = 75/100 = 3/4

2.00 - 1.00 = 1.00 = 100/100 = 1/1 or evens

## How do you convert from fractional to decimal odds?

1. Divide the first figure by the second figure
2. Add 1.00 to the result

For example, converting 10/11 from fractional to decimal odds:

10/11 = 0.909090 = 0.91

Adding 1.00 will give you 1.91

### American odds

What the hell are those American odds? +135 or -275?

Probably the most confusing odds format for most of the punters, apart from those from America of course, but generally also quite simple - the number represents the stake you need to place to make a profit of £100.
