## Betting odds converter

The betting odds converter converts betting odds between **Fractional Odds**, **Decimal Odds**, and **American odds** (Moneyline).

### What are betting odds?

The betting odds provide the ratio between the **winning** and the **wager**.

For example, if the odds are 5/2, for wager of $2, if you win you will win $5. In this case, the payment is $7, the wager ($2) plus the winning (5$).

### What is the difference between odds and betting odds?

In statistics **odds** are chances, similar to probabilities, while **betting odds** represent ratio between amounts.

If you know the betting odds you may calculate the winning probability that yield average of zero wining/losing amount. This is the implied Probability.

### Different odds format

**Fractional odds** - the format is **winning/wager**, like in the above example 5/2 **Decimal odds** - the ratio between the payout and the wager.**American odds**

Winning > wager: the percentage of the **winning** related to the **wager**. 100 * winning/wager=250.

Winning < wager: the percentage of the **wager** related to the **winning**, with a negative sign.

e.g wager ($5) winning ($2).

-100 * wager/winning = -250.**Implied Probability** - if the winning probability will be equal to the implied probability, then the average winning amount will be zero.

Example: if the odds are 3/1 (winning ($3), wager ($1), payment ($4)), then if the probability to win is 0.25:

p*payment - wager = 0.

0.25 * $4 - $1 = 0.

### Fractional odds to decimal odds formula

Decimal odds = 1 + | winning |

wager |

### Fractional odds to American odds formula

**Winning ≥ wager:**

American odds = 100 * | winning |

wager |

**Winning < wager:**

American odds = -100 * | wager |

winning |

### Decimal odds to Fractional odds formula

- Subtract 1
- Convert the decimal result to a fraction

### Decimal odds to American odds formula

- Decimal odds ≥ 2: 100 * (Decimal odds - 1)
- Decimal odds < 2: -100 / (Decimal odds - 1)

### American odds to Decimal odds formula

**American odds ≥ 0:**American odds/100 + 1**American odds < 0:**-100/American odds + 1

### American odds to Fractional odds formula

**American odds ≥ 0:**

American odds/100**American odds < 0:**

-100/American odds- Convert the decimal result to a fraction
