Free Betting Odds Converter
Instantly convert between decimal, fractional, American and Hong Kong odds — and see the implied probability. Free, accurate, and works on any device.
Tip: implied probability tells you the chance the odds suggest. Lower odds = higher probability. Use it to spot whether a market looks like value.
How to use the odds converter
Pick the format your odds are already in, type the number, and every other format updates instantly along with the implied probability. It's handy when one source shows decimal odds and another shows fractional, or when you want to quickly sanity-check whether a price represents value before placing a cricket trade on KingExch365.

Understanding implied probability
Implied probability is the single most useful number for a trader. For decimal odds it's simply 1 ÷ odds, shown as a percentage. If you believe the true chance of an outcome is higher than the implied probability, the odds may represent value; if it's lower, they probably don't. It won't make you win, but it turns gut feeling into a number you can compare. Learn more in our cricket trading guide or read the KingExch365 review.
