# Odds Format Transformation

{% hint style="info" %}
The data we provide is in European odds. If you wish to use odds in other formats, please convert them yourself according to the following rules.
{% endhint %}

## EU to UK

#### Formula: 

`Odds (UK) = Odds (EU) - 1, then display in fraction.`

Since there is a certain error after converting a decimal to a fraction, the fraction should be taken as close as possible to the original value. 

For example, the original value is 1.72, according to the formula above, UK = 1.72 – 1 = 0.72. There are two options close to it, 8/11 ≈ 0.727273 & 5/7 ≈0.714285. Given the fact that 5/7 has a smaller absolute difference, |0.72 - 0.714285|< |0.72 - 0.727273|, the result of UK value would be 5/7 in this case.

***

## EU to US

#### Formula:

`If Odds (UK) < 2,`

`Odds (US) = 100 / (1 - Odds (EU)), then round to the nearest whole number.`

`else,`

`Odds (US) = 100 * (Odds (UK) - 1), then round to the nearest whole number.`

#### Example:

**The market 1X2: Home=1.72; Draw=4.50; Away=3.75**

Home: 1.75 <2, US=100/(1-1.72)=-138

Away: 4.50 ≥2, US=100\*(1.45–1)=350

***

## EU to MA

#### Formula:

`If Odds (UK) < 2,`

`Odds (MA) = Odds (EU) - 1, then keep two decimals`

`else,`

`Odds (US) = 1 / (1 - Odds (EU)), then keep two decimals`

#### Example:

**The market 1X2: Home=1.72; Draw=4.50; Away=3.75**

Home: 1.75 <2, MA=1.72-1=0.72

Away: 4.50 ≥2, MA=1/(1-4.50)=-0.28

***

## EU to HK

#### Formula:

`Odds (HK) = Odds (EU) - 1, then keep two decimals`

#### Example:

**The market 1X2: Home=1.72; Draw=4.50; Away=3.75**

Home: HK=1.72-1=0.72

Away: HK=4.50-1=3.50

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://developer.aiodds.com/help-center/other/odds-format-transformation.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
