To convert this, we need to add the pot size and the amount to call and divide the amount to call by the total pot size. I think it is more valuable to see this as a percentage. Pot Size Versus Amount to Call = Pot Odds as Ratio e.g. Most poker players find it easier to understand things as percentages than ratios. It is usually expressed as a ratio however, the far more valuable tool is the conversion of ratio to percentage. Basically, pot odds are the comparison of the cost of making a call compared to the size of the pot. You have probably heard of pot odds but maybe you’re not sure what they are or how to calculate them.
