How converter works?

American odds to decimal formula

Positive Decimal = (American odds / 100) +1

Negative Decimal = (100 / American odds) +1

Decimal odds to american formula

Odds 2.0 or more American = (Decimal odds -1) * 100

Between 1.01 and 1.99 American = -100 / (Decimal odds - 1)

Decimal odds to implied profitablity formula

(1/ decimal odds) * 100 = implied probability

American odds to implied profitability formula

Positive 100 / (positive American odds + 100) * 100 = = implied probability

Negative Negative American odds / (Negative American odds + 100) * 100 = implied probability
