Betting Odds conversion chart

To understand what betting odds are, we have to first understand the concept of chance. Chance is the likelihood of an event happening. It is often expressed in percentages, also referred to as the probability.

Example: Roll a dice.

Rolling a dice yields a probability of 1 out of 6 for each outcome.

The chance of the dice landing on any of the 6 numbers is equal. In percentages this means a 16.66% chance (or probability) of any of the six numbers to coming up.

How is this calculated?

Simply by dividing 100% by the 6 possible outcomes.

There are three kinds of odds you will come across in the sports betting landscape.

  • Decimal Odds: represented as 1.65 or 2.95 etc.
  • Fractional Odds: represented as 5/2 or 3 to 2 ‘on’ etc.
  • Moneyline Odds: represented as -120 or +140 etc.

The following is an odds conversion chart that presents the odds and implied probability across each odds format.
