How the Odds Calculator Is Calculated

American odds are converted to decimal odds using odds/100 + 1 for positive odds or 100/|odds| + 1 for negative odds, and to implied probability using 100/(odds+100) for positive odds or |odds|/(|odds|+100) for negative odds — the standard conversions used across sportsbooks.
