Decimal odds are common in Europe, Canada, Australia, and many international sportsbooks. They show the total return multiplier, including your original stake. For example, decimal odds of 2.50 mean a 100-unit winning bet returns 250 units total.
US sportsbooks usually display prices in American odds, also called moneyline odds. This format uses plus and minus numbers to show underdog profit or favorite risk. This Decimal to American Odds Converter turns a decimal price into the US moneyline equivalent.
Quick examples: 1.50 converts to -200, 1.91 converts to about -110, 2.00 converts to +100, and 2.50 converts to +150.

Decimal vs American Odds
Decimal and American odds are two ways of displaying the same betting price. The format does not change the payout.
| Format | What it shows | Example |
|---|---|---|
| Decimal | Total return multiplier, including stake. | 2.50 means 2.5 units returned per 1 unit staked. |
| American / moneyline | Profit on 100 units or stake needed to win 100 units. | +150 means 150 units profit on a 100-unit winning bet. |
| Fractional | Profit as a ratio of stake. | 3/2 means 3 units profit for every 2 units staked. |
Important Limitation
This converter only changes the odds display format. It does not tell you whether the bet has value. To judge value, compare the break-even probability from the price with your own estimate of the outcome’s real chance.
