Odds Converter

Converts betting odds between the decimal, American, fractional, Hong Kong, Malay and Indonesian formats and shows the implied probability behind each price.

Notes

  • Implied probability = 1 / decimal odds. Bookmaker prices add up to more than 100% across a market; that surplus is the vig.
  • Hong Kong odds are the net profit per unit staked. Malay and Indonesian odds flip sign at even money: Malay is positive for favourites (decimal under 2.00), Indonesian is positive for underdogs (decimal over 2.00).
  • Gambling math is informational only, not betting advice. Gambling involves risk of loss; only play with money you can afford to lose, and only if you are 18+ (or of legal age where you live).
