All about our betting odds converter calculator

We believe that no gaming session is complete without our betting odds converter. Our team has spent a fair amount of time creating this stunning piece of kit. So what does our betting odds converter calculator do? Well, it takes some betting odds and converts them into another format. This means that you’ll instantly see what kind of return you’re getting from your bet even if you didn’t understand the original odds format.

Our betting odds converter is able to convert all of the odds formats out there. These include American odds, fractional odds, and decimal odds. All you have to do is to input the odds format, click which format you want to see the odds converted to and know whether you should take those odds or not. This means that you can pick any odds at any sportsbooks and instantly understand what’s on offer. If only quantum physics was so simple!

Why our betting odds converter is essential

Sports betting should be easy and fun. Understanding betting odds is one of the biggest causes of complaints for new players. Not only do you have to understand the basic concepts of probability, but there are at least three different odds formats that you’ll encounter. Thankfully our betting odds converter is here to save the day. Here are some reasons why you should pack our betting odds converter calculator at your disposal.

Convert the odds for the big game

Imagine that there’s a massive football game on and you want to bet on the Raiders to beat the Rams. The only problem is that the online sportsbook you were thinking of using only has fractional and decimal odds. You always use American odds format as it helps you spot the underdog, the favorite and know how much you’re getting back from your bets. This is where you’d simply launch our betting odds converter which instantly reveals the bets in your preferred odds format. This means that you can sit back and enjoy the big game without too much mental arithmetic.

Understand odds for all kinds of betting

Our odds converter can be used for pretty much any kind of sports bet you can think of. We find that it’s a great way of understanding what kinds of futures bets different sportsbooks have. After all, some sportsbooks will display the Super Bowl odds in American format, while other sportsbooks will have the NBA Finals odds in decimal format. The same is true for betting on anything from spread bets to player props. Most of us will be happy to use American odds formats, but some sportsbooks may have different ideas. Thankfully our betting odds converter will be by your side to help you out with any sportsbook you’ll meet.

How to use our betting odds converter calculator

We realize that it’s fairly easy to get wrapped up in scientific theory. This is especially true when it comes to discussing abstract properties like betting odds. So we thought that we’d lighten your load by giving you some quick and easy examples of how our betting odds converter works. Take a look below and see how this awesome piece of technology will make you’re pondering much simpler:

Converting fractional odds to American odds

We’re pretty sure that only a few people in the UK actually like using fractional betting odds. Plus there are some pretty good UK sportsbooks who have come to the US who still use fractional odds formats. So let’s imagine that you want to bet on a big Monday night football game and the sportsbook insisted on using fractional odds. Here you saw the Cleveland Browns with money line odds of 5/4 and New Orleans Saints with odds of 1/2. All that you have to do is to type in each of the fractional odds into our betting odds converter and you’ll instantly see the odds in American odds format. So it’ll show that the Browns had odds of +125 to win, while the Saints had odds of -200 to win. Much easier to know who the favorites are, who the underdogs are, and how much you’ll get back from your bets!

Converting American odds to decimal odds

American odds are great for some bets, but many newcomers may find that decimal odds are easier to understand. The good news is that our betting odds converter is simple enough to use so that even complete rookies can convert American odds to decimal. Imagine that there’s a big NBA game between the LA Lakers and the New York Knicks. The Lakers had money line odds of -150 to win, while the Knicks odds were +250. Here, you’d just input the information into our betting odds converter. This would instantly reveal the decimal odds to be 1.67 for a Lakers win, and 3.50 for a Knicks win. A great way for rookies to understand what’s most likely to happen in the big game.

Converting American odds to fractional odds

Fractional odds may look a little weird, but this odds format definitely has its uses. Our betting odds converter offers you a fast way to convert any odds into fractional odds. Let’s say that it’s the Stanley Cup final between Boston Bruins and Pittsburgh Penguins and you want to know which team will give you more for your bets. The Bruins had American odds of -200 to win, while the Penguins had winning odds of 200. You’d input the information into the odds converter and see the fractional betting odds for either team. This would show that the Bruins fractional odds were 1/2 which means that you’d get $1 for every $2 that you’d bet. However, the Penguin’s odds would be 2/1, meaning that you’d get $2 for every $1 that you wagered. An easy way to see the best value bets!

Tips for using any betting odds converter app

Our betting odds converter is designed to help you make sense of all of the different odds formats out there. While this is a simple premise, it’s up to you to make sure that you use it effectively. After all, you’ll get more out of sports betting, the more you put into it. So here are some ideas about the most effective ways that you can use our betting odds converter calculator:

Visit those distant sportsbooks:

Most online sportsbooks in the US will be homegrown, and will display the odds in decimal or American odds formats. However, you might occasionally encounter a European online sportsbook. Chances are that this sportsbook will only display the odds in either a decimal or fractional format. Here’s where you’d put our betting odds converter into action to see whether the odds can give you the edge with your bets. Just make sure that the betting site is fully regulated in the US first.

Understand how those bonuses work:

We’re all massive fans of welcome bonuses and betting promotions. But the small print in these deals can often be confusing. This is especially true when it comes to any bonus that has minimum or maximum betting odds. Here you might find that the odds are displayed in a format that you don’t understand. So launch our betting odds converter calculator and see whether that bonus is worth claiming or not.

Gain a greater understanding of how each bet works:

We think that all different odds formats have their uses. Our betting odds converter gives you a fast and easy way to switch formats and gain a greater understanding of what’s on offer. We love using the American odds format when there is a clear favorite and underdog. The decimal odds format is by far our favorite format when it comes to building that massive parlay. Even the fractional format can be a good way for understanding what kind of payout you’ll get. So be sure to play around with our betting odds converter calculator to boost your sports betting knowhow. 

More than one calculator to play with

We should note, our betting odds converter calculator isn’t the only sports betting odds calculator on our site. You’ll also find a range of bet calculators that are designed to take the pain out of working out how much a sportsbook is offering you with its bets. All of these calculators have been designed by our team. This means they’re easy to use and accurate. Here are just some of the betting calculators that we have to offer:

Betting odds calculator: This is our entry-level betting calculator that’s perfect for anyone who wants a simple way to work out what kind of payouts they can get from their bets. All that you have to do is to enter your betting stake, the bet type and the betting odds. Our bet calculator will then fire into action and instantly tell you what you could win. While this betting calculator is easy to use, it’s got enough to it to handle a range of parlays and exotic bets.

Parlay calculator: Parlay betting might be tricky, but our parlay calculator at least makes it easy to see what you’ll get paid. You can add selections to the calculator, enter your stake, and then stand back and see what giant-sized wins you can pick up. Our parlay calculator is also nicely customizable. This means that you can adjust what selections you include at any point. Add another selection to make an even larger win. Switch a selection to stop those odds from getting out of control. Try removing a selection completely to keep your parlay within the realms of possibility. All is possible with our parlay betting calculator.

Odds value calculator: This is the ultimate piece of kit for spotting when a sportsbook has overvalued its odds. Our odds value calculator is based on the mechanics of expected value and can identify value bets. The formula that it uses to do this is far too boring to be explained here, but it essentially means that a sportsbook is willing to pay you more than you should realistically get for that winning bet.

Don’t forget about the sportsbook’s odds format switcher: We’re doing ourselves no favors here, but it’s important to let you know that most online sportsbooks will have a feature that lets you switch the odds format. This can be found anywhere from the site footer to the header or even the sidebar. However, we should note that even the odds format switching tool might not have your preferred odds format. So make sure that you bookmark our betting odds converter!

Conclusion – Getting the most from our betting odds calculator

Our betting odds converter has given you the perfect way to know what any sportsbook is offering you. It doesn’t matter whether that sportsbook deals exclusively in American, decimal, or fractional odds. You can simply fire up our betting odds converter calculator and understand exactly what that sportsbook is offering. A great way to see whether the odds are worth betting on or not. Remember that our betting odds converter can only do so much. The real work begins when it comes to making your betting predictions. So let our betting odds converter calculator do the boring stuff, and you concentrate on predicting who’s going to win that big game!
