american odds is pretty easy. +130 means you win 130 for 100 wager, and -140 means you win 100 for 140 wager.

the formula to convert it to decimal odds is for all plus money odds, you just add 100 and divide it by 100. for example, +130 will be 2.30 in decimal odds.

for minus money, the math gets a bit harder. divid it by 100, take the inverse and add 1. for example, -140 will be 1.71 in decimal pricing.

as you can see it is pretty easy to go back and forth for plus money odds, but the real question is how do you convert minus money odds in your head? (don't really want to keep my spreadsheet open everytime i want to make a bet)

does anyone know the rational behind the decimal system? i am still puzzled why 2 is the even money bet? why don't they make 1 the even money bet, so you don't have to add one when you go from american to decimal.

The rational behind decimals is that it is simple and the accepted notation in most countries why bother with strange American odds when you can stick t decimals.

I prefer american odds as that's what I have always known. I rarely have to convert between them but if I do I just use this

for minus money, the math gets a bit harder. divid it by 100, take the inverse and add 1. for example, -140 will be 1.71 in decimal pricing.

To make it explicit:

For US odds ≤ -100:

                       100
Decimal odds = 1 - -----------
		     US Odds

For US odds ≥ +100:

                     US Odds
Decimal odds = 1 + -----------
		       100

And to convert from decimal to US:

For decimal odds ≥ 2: US = 100×(decimal-1)

For decimal odds < 2: US =    -100  (decimal-1) 

does anyone know the rational behind the decimal system? i am still puzzled why 2 is the even money bet? why don't they make 1 the even money bet, so you don't have to add one when you go from american to decimal.

The rationale is rather straightforward. Decimal odds represent the dollar amount returned to you on a win off a 1-unit bet including your original stake. For example:

• If decimal odds were 2.00 (US: +100), this would mean that if you were to bet $1.00 and win you'd be returned $2.00 ($1.00 in winnings plus your $1 original bet).
• If decimal odds were 1.50 (US: -200), this would mean that if you were to bet $1.00 and win you'd be returned $1.50 ($0.50 in winnings plus your $1 original bet).

Usually sportsbooks have a feature that allows you to select one or the other....

[WWTSblows]

Not always though. For the negative ones, I have the same system you do. I use a calculator on my desk for those.

If you are good at math, you can use that way to get close. Like knowing 14 goes into 100 roughly 7 times can get you to -170 in your head.

[pico]

is there anything you don't know about gambling? maybe i should just hire you as a consultant when i have a sizable amount of gambling money.

[Scorpion]

How about a formula for converting Fraction odds to US odds?
I know you can convert Fraction to Decimal and then to US

[Ganchrow]

How about a formula for converting Fraction odds to US odds?

Yeah, that's exactly it:

fractional = decimal - 1

Hence, to convert from fractional to US odds:

For fractional odds ≥ 1: US = 100×fractional

For fractional odds < 1: US =    -100  fractional

whats the math for odds like 10/11 or 9/5, how do i make that an American line?

[chandler1981]

LK,
just divide it and turn it into a decimal odd and then follow Gaunch's formula to make it american.

American odds are possibly the most pointless odds format there is. Decimals are much more informative and easier to use. The only time I need to convert to American odds is when I post in the Best Bets threads.

[TheCalculator]

Does anyone know the formula for converting % of wins into American odds or Fractionated odds?

e.g.
58.02% - Team 1
41.98% - Team 2

Thanks!

[a4u2fear]

for clarification, for decimale < 2, US = -100 / (decimal-1)

division was missing.

[jjgold]

Still to complicated

Fractional odds much easier or Hong Kong Odds
