How to Convert Decimal Odds to American Odds

Decimal odds are the world standard outside North America and represent the total payout (stake plus winnings) per $1 wagered. They make it easy to see potential returns at a glance.

Why convert? US bettors or anyone using sportsbooks that display moneyline odds often need to convert decimal odds to the American format to compare lines or shop for value.
Conversion Formula:
- If decimal odds >= 2.00: American = (Decimal - 1) * 100 (underdog, positive moneyline)
- If decimal odds < 2.00: American = -100 / (Decimal - 1) (favorite, negative moneyline)
Example: Decimal odds of 2.50 convert to +150 American. Decimal odds of 1.50 convert to -200 American.

This conversion is essential for comparing lines on different betting platforms and understanding implied probabilities in your preferred format.
