Quick Start: How to Use the Odds Converter
This tool switches any odds format (American, Decimal, or Fractional) into the other three, plus calculates the Implied Probability. This is the key to knowing what the bookmaker thinks your winning chances are, similar to checking the gas gauge before a road trip.
Step 1: Select Your Input Format
- Find the Buttons: Look for the three large buttons at the top of the calculator labeled American, Decimal, and Fractional.
- Tap to Choose: Click the button matching the odds format you currently have. The selected button turns blue to confirm your choice.
- Example: If you have “2.50”, select Decimal. If you have “+150”, select American.
Step 2: Enter the Odds Value
- Locate the Input Box: Find the field labeled “Enter Odds Value.”
- Type or Paste: Enter your odds number directly into this box. The hint text below the box changes to guide your input format.
- American: Enter the number with the sign (e.g., +150 or -200).
- Decimal: Enter the decimal number (e.g., 2.50).
- Fractional: Enter the fraction with a slash (e.g., 3/2 or 1/2).
Step 3: View Instant Conversion
- Click the Button: Press the large green Convert Odds button. The calculator processes the number.
- Review the Results: The “Converted Odds” section appears immediately below, showing all four calculated values:
- American Odds
- Decimal Odds
- Fractional Odds
- Implied Probability (shown as a percentage)
Why This Tool is Essential (The Clarity You Need)
Odds formats are confusing, like different languages for the same idea. An American odds of +150 means the same thing as a Decimal odds of 2.50 and a Fractional odds of 3/2. Using this converter ensures you compare different bookmakers correctly and understand the potential payout.
The Magic Number: Implied Probability
The most valuable result is the Implied Probability. This number is the betting market’s estimate of the event’s chance of happening.
- Example: Decimal odds of 2.00 convert to 50% Implied Probability. The market believes this outcome has a 50/50 chance. Knowing this percentage lets you decide if the risk is worth the reward. You compare the calculator’s percentage to your own assessment. If you think the chance is higher than the calculated percentage, the odds offer good value.
