US odds to decimals?

[natrass]

Bit stupid but how do you convert US style odds to decimals?

e.g.

Birmingham v Liverpool is

Bham +500. Lpool -200. Draw +270.

What would these be in good old deciamsl please?

US odds:

- Over 100, multiply by 1.0 for each 100. For instance, +500 = 5x and +270 = 2.7 x.
- Under 100, divide by the number. Here 100/200 = 0.5x

For the standard -110 that is: 100/110 = 0.909

How do you convert US style odds to decimals?

For US odds <-100:

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

For US odds >= 100:

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

Birmingham v Liverpool is

Bham +500. Lpool -200. Draw +270.

So:
Bham = 6.00
Lpool = 1.50
Draw = 3.70

Kind of interesting that 1 is added for decimals. That 1 is the money you risk.

In the US the only thing that counts is the profit.

Different philosophies?

Only in the case of a better than even money dog. If you're with a negative money line then "the only thing that counts" is the "at risk amount".

If you were to ask me, I'd say that the European decimal style is more intuitive.

Different philosophies?

Nah, just different dialects.

Perfact. thanks gents.

Yes, the adding the one is important. We also use fractions a lot and the stake isnt included there (ie 1.5 ... or -200??? ... is simply written as 1/2) ... go into any high street bookie and all the odds are in fractions. Until a couple of years ago I would translate decimals to fractions but now Ive got used to decimals ... they are perfect for odds comparisons and analysis.

I see "1" added always. +200 is not 2.00 but 3.00. In -200 it's not .5 but 1.5.

The above quote was made specifically in reference to US -style odds.

I personally like the decimals more. Might be obvious as i'm from Europe. Just seems much more convenient to me. Just multiply your stake with the decimal odd and you get the payout including your stake.

It's like the Metric System. It's so much more intuitive and much easier to manipulate mathematically, but Americans are too stubborn to take 3 seconds to learn it.
