WHY THIS TOOL
Six formats, one tap
Decimal, Hong Kong, American moneyline, Malay, Fractional and Indonesian — pick whichever you typed in, and the other five rewrite themselves the moment you stop typing.
Implied probability, every line
Every result card shows the implied probability under the headline number, so you can tell at a glance whether 1.91 (52.36%) is overpriced or 2.10 (47.62%) is closer to fair value — without doing the math in your head.
Free, no signup, no tracking
Open the page, type, read. No login, no email, no cookie wall — same as every XYES tool. Bookmark and come back the next time you're staring at a sportsbook line you don't recognise.
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 weird format the bookmaker decided to ship you. Here's the path from confusion to comparable.
- 01
Pick the format you're starting from
Decimal at most European books, American at every US sportsbook, Hong Kong on Asian sites, Fractional on UK racing — just tap whichever matches the number you've already got in front of you.
- 02
Type the line and your stake
Drop in the odds (we accept '+150', '3/2', '0.50', 'whatever') and your bet size. We default to $100 because that's how most bettors instinctively price a bet — adjust it to whatever you actually plan to put down.
- 03
Read across all six cards
Six conversion cards light up at once with the equivalent odds, the implied probability and a one-line reading guide. Hit Copy to grab a single text blob you can paste straight into Telegram for cross-checking.

FORMAT GUIDE
What each odds format actually means
Six ways of saying the same thing. The math is identical underneath — once you know how to read each format, switching between sportsbooks anywhere in the world stops feeling foreign.
Decimal odds — the simplest math out there
Decimal 2.50 means a $1 bet pays $2.50 back if it wins ($1.50 profit + your stake). It's the world's default because the multiplication is trivial: stake × decimal = total return.
Europe, Australia, Canada, most online sportsbooks
Hong Kong odds — Decimal minus one
Hong Kong 1.50 means a $1 bet wins $1.50 in profit (so $2.50 back including stake). Hong Kong is just Decimal minus one — easier for old-school punters who prefer profit-only numbers.
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 stake $200 to win $100. Negative odds always mark the favourite, positive odds the underdog.
United States, Las Vegas, North America
Malay odds — flipped sign on heavy favourites
Malay 0.50 reads exactly 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 line Hong Kong would write as 2.00, just expressed 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 South-East Asian bookmakers.
Indonesia, Thailand, the Philippines
WHO USES WHAT
Which regions use which formats
Different parts of the world picked different conventions decades ago, and the formats stuck. Here's what to expect when you land on a sportsbook somewhere new.
Hong Kong & Macau
Hong Kong odds
The default on most local sportsbooks. Most international books also offer a Decimal toggle for travellers.
United States
American moneyline
The only format on US books — even the regulated DFS apps. Negative for favourites, positive for underdogs.
United Kingdom & Ireland
Fractional
The standard at racing tracks and high-street bookmakers. Online sites usually offer a Decimal toggle.
Europe & Australia
Decimal
The world's de-facto digital standard — clean math, easy to compare across books at a glance.
Malaysia & Singapore
Malay & Hong Kong
Asian-handicap markets often quote Malay; mainstream straight bets default to Hong Kong.
Indonesia & SE Asia
Indonesian
Locally familiar variant of American. Most regional books also support Decimal and Hong Kong.
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.
