Stop searching for low-resolution images of betting charts. If you are a serious bettor, you need a reference table that matches your specific needs.
Our Odds Conversion Chart Generator is the ultimate reference tool. Unlike static tables, this tool allows you to define your own range (e.g., only looking at longshots) and step size. It instantly generates a clean, readable table comparing Decimal, American, and Fractional odds alongside their Implied Probability. Best of all, you can download the data as a CSV file to use in Excel or Google Sheets.

Why Use a Conversion Table?
While calculators are great for specific bets, a conversion chart is essential for spotting value at a glance.
Example 1: The Excel Modeler
You are building a betting model in a spreadsheet. You need to convert a column of 50 different Decimal odds into American odds for reporting. Instead of calculating them one by one, generate a table here, download the CSV, and use a VLOOKUP function in your spreadsheet to convert them instantly.
Example 2: The “Cheat Sheet”
You are watching a UK horse racing stream where they only use Fractional Odds (e.g., 7/2, 15/8). You are used to American Odds. By keeping a printed chart on your desk, you can instantly see that:
- 15/8 is roughly +188 (American) or 2.88 (Decimal).
- 7/2 is +350 (American) or 4.50 (Decimal).
Frequently Asked Questions (FAQ)
How do I convert Decimal to American odds?
If the Decimal is 2.00 or higher: (Decimal - 1) × 100. If the Decimal is less than 2.00: -100 / (Decimal - 1). Our chart does this math for you automatically across any range you select.
What is “Implied Probability”?
Implied probability is the percentage chance of winning reflected by the odds. For example, Decimal odds of 2.00 imply a 50% chance of winning. If you believe the true probability is 55%, you have a value bet.
Can I print this odds chart?
Yes. The best way to print is to click “Download CSV,” open the file in Excel or Google Sheets, format it to your liking (fonts, colors), and print it from there for a perfect layout.
