How to convert American odds

Negative odds (favorite): decimal = 1 + 100 / |odds|, so -110 is 1.91. Positive odds (underdog): decimal = 1 + odds / 100, so +150 is 2.50.

Implied probability is 1 divided by the decimal odds: -110 means 52.4%, +150 means 40%.

Payout and profit

Total payout = stake × decimal odds. Profit = payout minus stake. A $100 bet at -110 pays $190.91, a profit of $90.91.
