With an abundance of online convertors available, have you ever wondered how you can easily convert decimal to American odds and vice versa without using a calculator? Here’s the answer.
Read about the difference between American odds and Decimals odds formats.
The most common odds formats are the Decimal and the American odds. If you have been betting with European bookmakers, you are most likely used to Decimal odds. Before diving into the nitty-gritty of how to convert Decimal into American odds, though, there is one point that we need to clarify first.
A key difference between Decimal and American odds (also known as “money line odds” or simply “lines”) is that the US odds are quoted both in positive and negative numbers, which means that there are two formulas we need to make use of depending on whether the Decimal odds are greater or less than 2.00, resulting in positive or negative US odds respectively.
The positive figures represent the amount a player will win, if he bets 100 units of any currency. US odds of -150, for example, mean that you need to risk $150 for a net profit of $100. The negative figures, on the other hand, represent the amount you need to bet in order to make $100 of net profit.

Converting from Decimal to American odds
To convert a Decimal odd of 2.00 or greater, you follow the below formula:
US odds = (Decimal – 1) x 100
To see how it works in practice, here’s is the calculation of converting the odds of 2.50 and 5.40 in US-style format.
Decimal odds = 2.50
US odds = (2.50 -1) x100 = 1,50 x 100 = +150
Decimal odds = 5.40
US odds = (5.40-1) x 100 = 4.40 x 100 = +440
To convert a Decimal odd of less than 2.00 in US format, you use the below formula instead:
US odds = (-100)/(Decimal -1)
Let's convert now the odds of 1.50 and 1.80 in US format:
Decimal odd = 1.50
US odds = (-100)/(1.50-1) = (-100)/0.50= -200
Decimal odd = 1.80
US odds = (-100)/(1.80-1) = (-100)/0.80= -125
Converting from American to Decimal odds
If you are exclusively familiar with American odds, here are the only two rules you will ever need to remember in order to convert any US odd into its Decimal counterpart.
For positive US odds, divide the money line by 100 and add 1.
Decimal odds = (US odds/100) +1
Let’s take +200 and +600, for example:
US odds = +200
Decimal odds = (200/100) + 1 = 2 +1 = 3.00
US odds = +600
For negative US odds, divide 100 by the US odds disregarding the negative sign and add this value to 1.00
Decimal odds = (600/100) + 1 = 6 +1 = 7.00
Decimal odds = (100/US odds) + 1
Here’s how converting the odds of -130 and -900 into Decimal-style works:
US odds = – 1.30
(100/130) +1 = 0.769 + 1= 1.769
US odds = -900
(100/900) +1 = 0.111 + 1 = 1.111
