Convert Meters to Feet
Quickly switch meters into feet for height comparisons, climbing elevation, ceiling clearances or US construction plans.
1 m = 3.2808 ft
One metre equals approximately 3.28084 feet. To convert metres to feet, multiply by 3.28084 — so 10 m = 32.81 ft and 100 m = 328.08 ft. The underlying definition is exact in the other direction: a foot is precisely 0.3048 m, so 3.28084 is that reciprocal rounded to six figures. For quick estimates, tripling and adding ten percent gets within half a percent — 25 m becomes 75 plus 7.5, or about 82 ft against the true 82.02. The everyday case is height, where the decimal remainder is the trap: 1.8 m is 5.91 ft, which reads as 5 ft 11 in rather than 5 ft 9 in, because the 0.91 is a fraction of a foot and must be multiplied by twelve. Aviation keeps feet worldwide for altitude, which is why flight levels stay in feet even in metric countries.

How do you convert meters to feet?
Formula: feet = metres × 3.28084 • A 25 m competition swimming pool → 25 × 3.28084 = 82.02 ft, which is why US short-course pools at 25 yards (75 ft) are noticeably shorter. • A 1,500 m cruising altitude → 1,500 × 3.28084 = 4,921 ft, close to the 5,000 ft figure used in aviation radio calls. • A 3 m ceiling height → 3 × 3.28084 = 9.84 ft, just under the 10 ft often quoted in US property listings.
When and why people use meters to feet
Aviation is the most safety-critical application. Altitude is reported in feet across almost all of world aviation, including in countries that are otherwise fully metric, while terrain and obstacle data is often published in metres. Converting reliably matters because a mistake puts an aircraft at the wrong flight level. Property and construction come next. US listings quote ceiling heights, room dimensions and lot frontage in feet, while architectural drawings originating in Europe or Asia use metres. Anyone comparing a floor plan across the two systems needs the conversion, and the difference between a 2.4 m and an 8 ft ceiling — 7.87 ft versus 8 ft — is small but real. Sport is the third. Track events, swimming and field events are metric worldwide; American football, golf and some athletics reporting stay imperial. Converting lets a 100 m sprint time be compared meaningfully with a 100-yard one, which is 8.4% shorter.
Common mistakes to watch for when converting meters to feet
The main trap is converting to a decimal number of feet and then reading the decimal as inches. 4.5 feet is 4 feet 6 inches, not 4 feet 5 inches — the fractional part must be multiplied by 12. A second is the rounding shortcut of 3.3, which carries a 0.6% error; over a 300 m building that is nearly 2 m of accumulated discrepancy. A third is the survey foot, which differed from the international foot by two parts per million and was used in US state plane coordinate systems; NIST deprecated it at the end of 2022, but older survey data still carries it and the difference is significant over long distances. Finally, altitude in aviation is pressure altitude, not a physical height above ground, so converting the number does not make two figures directly comparable.
How to estimate meters to feet in your head
Multiply by 3 and then add a further 10% of the original. For 25 m: 25 × 3 = 75, plus 2.5 gives 77.5 ft against a true 82.0 — that shortcut is about 5% low, so a better version is to multiply by 3 and add a third of the original: 75 + 8.3 = 83.3, now about 1.5% high. The cleanest practical anchor is that 3 metres is very nearly 10 feet (9.84), so metres to feet is roughly 'multiply by 10, divide by 3'. For 25 m that gives 83.3 ft, the same result with easier arithmetic. For aviation-style figures, 300 m is about 1,000 ft, so a 3,000 m altitude is roughly 10,000 ft. The error is about 1.6% low, which is acceptable for orientation and not acceptable for a flight level.
Meters to Feet FAQ
How many feet is a metre?
- About 3.28084 ft. The exact definition runs the other way — a foot is precisely 0.3048 m.
How do I express the result in feet and inches?
- Take the decimal part of the feet figure and multiply it by 12. So 9.84 ft is 9 feet 10.1 inches.
Is 3.3 accurate enough as a shortcut?
- It is 0.6% high. Fine for a rough sense of scale, but over 300 m it accumulates to nearly 2 m of error.
Why does aviation use feet if the world is metric?
- Historic standardisation. ICAO permits feet for altitude and it remains near-universal outside a handful of countries, so altimeters and clearances stay in feet.
What is the US survey foot?
- A legacy unit differing from the international foot by two parts per million, used in state plane coordinates. NIST deprecated it at the end of 2022.
How tall is a 2.4 m ceiling in feet?
- 7.87 ft — slightly under the 8 ft standard common in US residential construction.
Is a 100 m sprint the same as a 100-yard dash?
- No. 100 m is 109.36 yards, so the metric sprint is about 8.4% longer.
Is my input transmitted anywhere?
- No. The calculation is performed locally in your browser.
