Odds Converter
Convert six odds formats and view implied probability.
Fractional: 3/2. American: +150 or -200. Switching format preserves the unrounded conversion.
Odds conversions are mathematical estimates, not betting advice.
Convert decimal, American, fractional and Asian odds formats
Compare equivalent prices expressed as decimal, American, fractional, Hong Kong, Malay and Indonesian odds. The converter also displays the implied probability associated with the entered price.
How to use it
- Select the format of the original odds and enter its value.
- Read the six converted representations and the displayed implied probability without re-entering rounded outputs.
Worked example
Decimal odds of 2.50 correspond to American +150, fractional 3/2 and an implied probability of 40%.
How the result is calculated or checked
For decimal odds, implied probability (%) = 100 ÷ decimal odds. Conversions use the same underlying price; display rounding does not change that price in the calculation engine.
Frequently asked questions
- Does implied probability predict the true chance of winning?
- No. It is the probability represented by the quoted odds. Bookmaker margins and pricing assumptions can make it different from a true event probability.
- Why do some converted figures show decimals?
- Different odds systems represent and round the same underlying price differently. Retain the original precision when comparing results.
Odds conversion is arithmetic only; it does not recommend a bet or assess a fixture.
