# How to Convert American Odds to Fractional?

Let’s look at how you can convert American odds to fractional odds.

## Understanding American & Fraction Odds

American odds are predominantly used in the US and are either positive or negative. Positive odds indicate how much profit you would earn on a \$100 stake, while negative odds show how much you need to stake to win \$100. Fractional odds, commonly used in the UK and Ireland, display the potential profit relative to the stake.
