Golf Course Distance and Yardage Converter
Golf Course Distance and Yardage Converter
Yards to metres and back, for a scorecard printed in the other system. The factor is exact and definitional — a yard has been 0.9144 metres since 1959 — so this converter has no approximation in it anywhere, which is rarer on a golf page than it sounds.

The factors, and why they are exact
1 yard = 3 feet = 36 inches
1 mile = 1,760 yards
- 0.9144, exactly
- fixed by the 1959 agreement quoted in the section below, which made the inch exactly 25.4 mm — so the yard is 0.9144 m by definition rather than by measurement
- 3 and 36 are definitional too
- three feet and thirty-six inches to the yard are definitions rather than conversions, so the foot and inch rows carry no additional rounding
- 1,760 is not quoted from NIST
- the NIST page used here does not state the mile in words, so the mile row is 1,760 yards by the historical definition of the statute mile — exact, but taken from the definition rather than from that page
- what this converter will not do
- it converts a distance you already have. It does not rate a course, because a Course Rating is issued by an Authorized Association under the World Handicap System and is not arithmetic anybody can do from a yardage
Worked example
150 yards, the stock approach distance
150 × 0.9144 = 137.16 metres, shown as 137.2 at the row's precision — exact arithmetic on an exact factor
The same 150 yards is 450 feet and 5,400 inches, both by definition
Switch the input unit to metres and enter 150 and the answer goes the other way: 150 m is 164.0 yards, which is why a card in metres plays longer than the same number in yards
A par-72 course of 6,500 yards is 5,943.6 metres; the same course printed as 5,943 metres would read 6,499.3 yards
A ten-foot putt is 3.05 metres — while the club-lengths Rule 19.2c's lateral relief are measured in are deliberately not a distance at all, so they are not in the ladder above
Walking 6,500 yards of holes is 3.69 miles before a single stroke goes sideways
Distances a golfer actually uses, in both systems
| Distance | Yards | Metres | What it is |
|---|---|---|---|
| A long putt | 10 yd | 9.1 m | 30 feet, and the usual limit of a realistic first putt |
| A short pitch | 30 yd | 27.4 m | where most up-and-downs are made or lost |
| The stock approach | 150 yd | 137.2 m | the distance most golfers know their club for |
| A long par three | 230 yd | 210.3 m | about the limit for one shot |
| A par four | 420 yd | 384.0 m | two shots and two putts |
| A par five | 540 yd | 493.8 m | three shots and two putts |
| Eighteen holes | 6,500 yd | 5,943.6 m | a full course, which is 3.69 miles of holes and rather more of walking |
Where golf stops using yards
| Measurement | Unit the Rules use | Why |
|---|---|---|
| Relief from an unplayable ball, lateral | two club-lengths | Rule 19.2c measures from the reference point in club-lengths, not in a unit of distance at all |
| Relief back on the line | one club-length | Rule 19.2b’s relief area, measured from where the ball first touches the ground |
| A putt | feet, by convention | nothing in the Rules measures a putt; feet are simply what players and broadcasters use |
| Hole yardages on the card | yards or metres | whichever the club prints. Neither is required by any rule, which is the reason this converter exists |
An exact factor, which is rarer than it sounds
Golf is played on a course measured in two different systems and printed on cards that rarely say which. American and British courses print yards; most of continental Europe, Japan and Australia print metres; a scorecard in one and a rangefinder in the other is an ordinary afternoon. The arithmetic is thankfully exact: a yard is 0.9144 metres, by definition rather than by measurement, so nothing on this page is approximated.
That exactness has a date. NIST records that “In 1958, a conference of English-speaking nations agreed to unify their standards of length and mass, and define them in terms of metric measures”, and that the resulting factors were announced “in 1959 in Federal Register Notice 59-5442 (June 30, 1959)”, making the inch “exactly equivalent to 25.4 mm”. Before that agreement the American and the imperial yard were genuinely different lengths — “The American yard was shortened and the imperial yard was lengthened as a result” — which is a real if historical reason a very old course measurement might not mean quite what you think. Since 1959 a yard is a yard everywhere.
What this converter will not do is worth stating as plainly as what it will. It converts a distance you already have. It does not rate a course: the Course Rating and Slope Rating printed on a scorecard are issued to a club by an Authorized Association under the World Handicap System, and they are not arithmetic anybody can perform on a yardage — length is one input among many. The World Handicap System page sets out who issues what and why this site computes none of it.
One quiet point about the Rules of Golf and distance: they set no course dimensions whatsoever. There is no minimum length for a par four, no specified distance from tee to green, nothing of the kind. That is a genuine difference from most sports, where the playing area is regulated to the centimetre, and it is why the distances in the first table are conventions rather than regulations. Where the Rules do measure, they often avoid units of distance altogether: Rule 19.2c’s lateral relief is “two club-lengths” from the reference point and Rule 19.2b’s relief area is “one club-length”, measured with something the player is already carrying rather than paced out in yards.
For the same definitional factor behind another sport’s distances, the pace unit converter turns on the same 0.9144 and the same NIST notice, which makes it the only other record in the plugin that depends on them. Within golf, the greens in regulation and putts calculator is where the approach distances in the table above turn into a statistic, and the penalty strokes and relief page covers the Rules whose relief areas are measured in club-lengths.
Frequently asked questions
How many metres is 150 yards?
137.16 metres, exactly. A yard has been defined as 0.9144 metres since the 1959 international agreement, so the conversion is a definition rather than a measurement and involves no rounding at any point.
Why do some scorecards use metres and some yards?
Because nothing requires either: the Rules of Golf set no course dimensions and name no unit, so clubs follow local custom — yards in Britain, Ireland and the United States, metres across much of the rest of the world. A course printed in metres plays about ten per cent longer than the same numbers in yards.
Is the conversion exact or approximate?
Exact. The 1959 factors made the inch “exactly equivalent to 25.4 mm”, which fixes the yard at 0.9144 m by definition rather than by measurement, and the feet and inches rows are definitional too.
Can I work out a course’s Course Rating from its yardage?
No. A Course Rating and a Slope Rating are issued to a golf club by an Authorized Association under the World Handicap System — Rule 1.2 of the Rules of Handicapping lists “Issue a Course Rating and a Slope Rating” among an Authorized Association’s powers — and length is only one of the things they take account of. They are printed on the scorecard for you.
How far is a club-length?
It depends on your clubs, which is the point. Rules 19.2b and 19.2c measure relief areas in club-lengths rather than in yards or metres so that a player can measure them with what they are carrying. The Rules put no distance on it, and neither does this page: there is nothing there to convert, which is why those rows sit in a table of their own.
