Odds Converter
Odds formats are display conventions — the underlying probability is identical regardless of whether you are looking at decimal 2.0, American +100, fractional 1/1, or implied 50%. The format varies by market and region; sharp bettors need to move fluently across all four.
Enter any format in the field below and read the other three instantly. The static reference table at the bottom covers the most common lines — useful as a quick mental conversion chart when comparing prices across books.
Input format
| Format | Value |

Worked examples
Example 1 — Even money
Decimal 2.0 is the simplest even-money line: you double your money if you win. In American odds that is +100 (stake $100, profit $100). In fractional odds it is 1/1 (evens). The implied probability is 50% — the book prices both sides as equally likely.
Example 2 — De-juiced standard line
The industry-standard juiced line on a 50/50 market is 1.91 decimal (both sides). In American: -110 (stake $110 to profit $100). In fractional: 10/11. The implied probability is 52.36% — each side above 50% because the book takes 4.5% margin across the market. Pinnacle's de-juiced line on the same market would be approximately 1.98/1.98.
