What is the Odds Converter?
Every odds format says the same thing in a different language: how much a bet pays relative to its risk, which also implies how often it needs to win to break even. This tool converts instantly between American (-110), decimal (1.91), fractional (10/11), and implied win probability (52.4%).
How to use it
1.Type odds into any of the four fields.
2.The other three formats update as you type.
Example
-110 in American odds is 1.91 in decimal, 0.91 in fractional, and implies a 52.38% win probability — that's the break-even rate for a standard -110 bet.
