You’re watching an American betting tip on YouTube and they’re talking about +150 and -200, and you’re sitting there like “bro, just tell me the normal odds.” This calculator is your translator.

What It Does: Converts odds between three formats: Decimal (what we use in Nigeria), Fractional (what UK people use), and American (what confuses everybody). Plus it tells you the implied probability, which is basically the bookie’s prediction of how likely something is to happen.

Why You Care: Because the internet is global now. That betting expert on Twitter might drop a tip with fractional odds like 5/2, and you’re googling “what does 5/2 mean” at midnight. Or you’re reading an article about NFL betting and everything is in American odds. This tool makes you multilingual in betting.

How to Use It:

1. Click the tab for the odds type you have (Decimal, Fractional, or American)
2. Type in the odds
3. Watch it convert to all three formats automatically
4. Check the implied probability to see if the bet even makes sense

Quick Lesson:

• Decimal odds (like 2.50) mean you get back 2.50× your stake if you win. So ₦1,000 becomes ₦2,500.
• Fractional odds (like 3/2) mean you profit 3 for every 2 you stake, plus you get your stake back.
• American odds with a plus sign (like +150) mean you win that amount per ₦100 staked. With a minus sign (like -200), you need to stake that amount to win ₦100. Yes, it's unnecessarily complicated.

Real Example: Your friend texts you "bet on this, odds are 6/4." You type that into the fractional tab. Boom, it converts to 2.50 decimal odds and tells you there's a 40% implied probability. Now you can decide if it's worth it.

Pro Tip: The implied probability is actually fire. If the calculator says 40% implied probability but YOU think it's more like 60%, that's a value bet. You're basically saying the bookie is wrong and underestimating the chances. That's where smart money is made.
