This guide simplifies the conversion process between decimal, fractional, American, and probability odds. Ideal for bettors of all levels, this page is your go-to resource for understanding and converting odds.

## Decimal Odds

Decimal odds are straightforward, indicating the total payout for every $1 wagered.

**Example:** 3.00 (wager $1 to receive $3).

**Conversion Formula:**

- To Fractional: Decimal Odds−1Decimal Odds−1 converted to a fraction (e.g., 3.00 – 1 = 2/1).
- To American: If the decimal odds exceed 2.00, multiply by 100 (e.g., 3.00 * 100 = +200). If less than 2.00, multiply by -100 and divide 1 by the decimal odds minus 1 (e.g., −1001.50−1≈−200−1.50−1100≈−200).

## Fractional Odds

**Explanation:** Fractional odds, favored in the UK, display the profit relative to the stake.

**Example:** 5/1 (bet $1 to win $5).

**Conversion Formula:**

- To Decimal: Convert to a decimal and add 1 (5/1 + 1 = 6.00).
- To American: If the fraction equals or exceeds 1 (e.g., 5/1), multiply by 100 (500). If less than 1 (e.g., 1/5), it’s negative and calculated as −100Fraction−Fraction100 (e.g., -500).

## American Odds

American odds, or moneyline odds, are expressed as positive or negative numbers.

**Example:** +200 (bet $100 to win $200) or -150 (bet $150 to win $100).

**Conversion Formula:**

- To Decimal: If positive, divide by 100 and add 1 (e.g., 200100+1=3.00100200+1=3.00). If negative, −100Odds+1−Odds100+1 (e.g., −100−150+1≈1.67−−150100+1≈1.67).
- To Fractional: Convert positive odds to a fraction of the odds over 100 (e.g., 200/100 = 2/1) and negative odds as -100 over the odds (e.g., -100/-150 = 2/3).

## Probability

Probability odds express the likelihood of an event occurring in percentages.

**Example:** 50% (50% chance of the event occurring).

**Conversion Formula:**

- To Decimal: 100Probability %Probability %100.
- To Fractional: Convert the percentage to a fraction and simplify (e.g., 50% = 50/100 = 1/2).
