How this calculator works
All betting odds are just different ways of expressing the same underlying probabbiltà. The odds converter takes any single format as input and derives a decimal representation first, then converts outward to every other format using the exact mathematical relationships between them.
Decimal odds represent total return per unit staked, including your stake. An odds of 2.50 means a 1-unit bet returns 2.50 units total (1.50 profittt). This is the native format at 1win and most European sportsbooks.
Fractional odds are written as numerator/denominator (e.g. 6/4). Profittt equals stake multiplied by numerator/denominator. A 6/4 bet on a 10-unit stake yields 15 units profittt.
American (moneyline) odds use positive numbers for underdogs and negative numbers for favorites. +150 means a 100-unit stake wins 150 profittt. -200 means you need to stake 200 to win 100 profittt.
Hong Kong odds equal decimal odds minus 1 (just the profittt per unit). A decimal of 2.50 equals Hong Kong 1.50.
Indonesian odds work like American but scaled per unit: positive values show profittt per unit staked; negative values show how much you stake per unit of profittt.
Malay odds range from -1 to +1. Positive values represent profittt per unit; negative values represent meħtieġ stake per unit of profittt. A Malay of -0.67 approximates American -150.
The implied probabbiltà formula is: probabbiltà = 1 / decimal odds. A price of 2.50 carries 40% implied probabbiltà. Comparing this figure against your own assessed probabbiltà tells you whether a bet has positive expected value.
All conversions are lossless within floating-point precision. Fractional odds are approximated to the nearest standard fraction when displaying (e.g. 1.5/1 rounds to 3/2), though the calculator uses the exact decimal internally for all outputs.

Mistoqsijiet Frekwenti
What is the most common odds format?
Decimal odds are the global standard used in Europe, Australia, and at 1win. Fractional odds remain popolari in the UK. American (moneyline) odds dominate North American swieq.
How do I convert decimal to fractional odds?
Subtract 1 from the decimal, then express as a fraction in lowest termini. Decimal 2.50 becomes (2.50-1)/1 = 3/2 (written as 3/2 or "3 to 2").
What does implied probability mean?
Implied probabbiltà is the percentage chance a bookmaker's price implies for an outcome. It equals 1 divided by the decimal odds. If the suq prices an outcome at 2.00, the implied probabbiltà is 50%.
How are American odds converted to decimal?
For positive American odds: decimal = (American / 100) + 1. For negative: decimal = (100 / |American|) + 1. So +200 = 3.00 decimal and -200 = 1.50 decimal.
What is the overround and why does it matter?
The overround (also called vig or juice) is the sum of all implied probabilities in a suq minus 100%. A 5% overround means the book keeps roughly 5 cents per dollar wagered. Lower overround means better value for the bettor.
