HOW IT WORKS
From any odds line to all six in under 10 seconds
The math is the easy part. The hard part is reading whatever odds format a sportsbook puts in front of you. Here is the fast path from confusion to comparison.
- 01
Pick the format you're starting from
Decimal odds are common across Europe, Australia, Canada and global crypto sportsbooks; American moneyline odds are standard in the US; Fractional still appears in UK and Irish racing; Hong Kong, Malay and Indonesian prices show up across Asian books. Tap the format that matches the number on your bet slip.
- 02
Type the line and your stake
Enter the odds — for example +150, -110, 3/2, 2.50 or 0.95 — and your stake. The default is $100 because it makes American odds and payout math easy to compare, but you can change it to the amount you actually plan to bet.
- 03
Read across all six cards
The result cards show equivalent odds, implied probability and a short reading guide. Use Copy if you want one clean text block to send to a host or compare with another sportsbook.

Quick conversion formulas
These are the fast formulas players use most often when checking a line across regions.
Hong Kong → Decimal
Hong Kong + 1
Example: 0.95 + 1 = Decimal 1.95.
Decimal → Hong Kong
Decimal - 1
Example: 2.50 - 1 = Hong Kong 1.50.
Positive American odds
+150 = $100 wins $150
Positive usually means an underdog or higher-return side.
Implied probability
1 ÷ Decimal × 100
Example: 2.00 = 50%; 1.50 = 66.67%.
Common conversion
+150 = 2.50 = 3/2
American +150, Decimal 2.50 and Fractional 3/2 are the same price.
Negative moneyline
-110 ≈ 1.91
A -110 line means you stake $110 to win $100 in net profit.
FORMAT GUIDE
What each odds format actually means
Six ways of saying the same thing. The math is identical underneath — once you can read each format, switching between sportsbooks in different regions is much easier.
Decimal odds — the simplest math out thereSOURCE
Decimal 2.50 means a $1 bet returns $2.50 if it wins ($1.50 profit + stake). It is the global default because the math is direct: stake × decimal odds = total return.
Europe, Australia, Canada, global crypto sportsbooks
Hong Kong odds — Decimal minus one
Hong Kong 1.50 means a $1 bet wins $1.50 in profit, so the total return is $2.50 including stake. Hong Kong odds are decimal odds minus one, which makes profit easier to read.
Hong Kong, Macau, Asian sportsbooks
American moneyline — used by every US sportsbook
American +150 means a $100 bet wins $150 profit. American -200 means you have to bet $200 to win $100. Negative odds mark the favorite; positive odds mark the underdog.
United States, Las Vegas, North America
Malay odds — flipped sign on heavy favorites
Malay 0.50 reads like Hong Kong 0.50. Above even money it flips negative — Malay -0.50 means stake 0.50 to win 1.00, which is the same price Hong Kong odds would express as 2.00 from the other side.
Malaysia, Singapore, Indonesia
Fractional odds — UK racing standard
Fractional 3/2 means three units of profit for every two units staked, plus your stake back. UK and Irish racing use this almost exclusively — '6/4', 'evens', '5/2' is how the announcer calls it.
United Kingdom, Ireland, racing tracks
Indonesian odds — American divided by 100
Indonesian odds are American odds divided by 100. +1.50 Indo equals +150 American; -2.00 Indo equals -200 American. Common across Southeast Asian sportsbooks.
Indonesia, Thailand, the Philippines
All conversions are pure math and identical across every regulated sportsbook — but the specific lines you see on XYES will differ from any other book by exactly the margin each book takes. Use this tool to compare formats, not to predict the future.

Common questions about odds conversion
The questions players ask before they bet — what each format actually means, why implied probability matters, how Fractional approximates, and whether the math is the same on every sportsbook.
What do +150 and -110 mean in American odds?
Are Decimal odds total payout or profit only?
How do I convert Fractional odds like 5/2 or 6/4?
Which odds format is best for comparing sportsbooks?
Are Hong Kong 0.95 and Decimal 1.95 the same line?
How is implied probability calculated from betting odds?
Why can converted payout differ from the sportsbook's final payout?
Does converting odds remove sportsbook margin or vig?
