Geographical odds formats - changes over time

Historically, fractional betting odds formats were the standard format used by most UK sportsbooks and physical betting shops; decimals used to be mainly used in Eurozone sportsbooks; USA odds were, as the name suggests, mainly used in the USA. Fractions are still the most prevalent odds format in the UK and most UK bookmakers still have their default odds settings within their websites fixed at fractional. However, with the introduction of betting exchanges and younger bettors seemingly preferring the decimal formats for easier calculations, the need to be aware of how these odds convert has become of higher demand.

Welcome the betting odds convertor

So, we thought it was about time to give the betting public what they need, without the need to solve a long mathematical equation, just to convert 9/4 into the 3.25 odds in decimal. Below, we will discuss why we think you’ll like our new betting odds convertor calculator.

Why you need a Betting Odds Converter - speed is of essence

Some of our betting experts at betting.net™ remember the days of having to convert fractions to decimals or decimals to USA odds. Thankfully, those days are long behind us, and we cannot wait to present our new free betting calculators available.

Years ago, a bettor would need to convert an equation, similar to the one found below

For 13/8 odds:

13 divided by 8 is equal to 1.625, add a whole number 1 = 2.63, when rounded-up.

The process of calculating this in reverse, from decimals to fractions is a harder process.

For the sake of your sanity and preservation of your time, it is a wiser choice to use a sports betting odds calculator such as the betting odds convertor that can be found on this page, free to use. Within this calculator are all the necessary mathematical formulas programmed algorithmically for speedy use. Now you do not need to trawl through website settings, or worry if you think you are unsure of the odds available, the answer is at hand, one click away. A good idea would be to bookmark this page for convenience.

Examples of everyday uses

Betting exchanges are becoming ever more popular in modern day betting and many bettors are now choosing to have the choice of betting with several sportsbooks and a betting exchange. The reason they like this is that having these numerous choices ensure that the bettor is more likely to obtain the best value prices on the market, when having more options at hand.

Problems can occur when the bettor is not familiar with the compulsory decimal odds format found on the betting exchange and they can find themselves in unfamiliar territory, not knowing how to evaluate a potential bet, due to being unaware of the true reflection of the betting odds in decimal format.

Why you need to use Betting Odds Converter - Knowledge is power

The need for using a betting odds calculator is increased if a bettor practises strategic betting. This technique requires the bettor to make fast decisions, as betting odds do not remain the same for long, and opportunities can pass in a fleeting moment. Therefore, having a tool like the betting odds convertor calculator found on this page will help in situations like this. Granted, if someone is a very regular bettor and uses this tool often enough, the need to keep visiting it will decrease a lot. Repetition ingrains knowledge and the bettor will inadvertently find themselves becoming very sharp at knowing how to convert decimals to fractions, vice versa, or even US odds to decimals, for example.

The recent legalisation of many betting states within the USA has also led to many new sportsbooks being introduced in America. The default setting for these sportsbooks will, of course, be USA odds which are very different to both fractions or decimals formats.

A typical American moneyline odds may look like this NFL game, below.

USA odds

-100 Baltimore Ravens
-110 Cleveland Browns

As you can see, these odds look very unfamiliar. But once we plug those odds into the betting odds convertor they make more sense to us:

Fractional

EVENS Baltimore Ravens
10/11 Cleveland Browns

Decimal

2.0 Baltimore Ravens
1.91 Cleveland Browns

It is amazing how just a simple visual representation displaying familiar odds changes our perception on whether we think we'll bet on the event we are looking at. We can quickly evaluate if we think the bet is worth it or not.

Top tips for using the calculator for the first time - common mistakes

When using this interesting calculator for the first time you will want to make sure you input all the data correctly, here's some tips we have found helps:

Slow down

This might seem counter-intuitive, especially when looking for the best odds, which sometimes are short-lived. However, it is better to get familiar with the new tool and not make any costly mistakes.

Become familiar

As mentioned earlier, this tool will prove an educational tool just as much as a workhorse! It will not be long before you are able to impress your fellow betting buddies with your slick instinctive odds converting skills.

Palpable errors

Palpable errors are an erroneous price that displays on a bookmakers website or comparison site. The word “palpable” is a word bookmakers use for noticeable mistakes. We recommend double-checking if you ever witness any odds that seem too big. In horse racing, non runners are the main cause for this.

Other calculators we offer - all free to use

If you have enjoyed our betting odds convertor app, then why not take a look at the other sportsbetting odds calculator versions that we have on betting.net™.
