How many feet are in a nautical mile?
One nautical mile is 6,076.11548556 feet, usually quoted as 6,076.1 ft. It is defined as exactly 1,852 metres, which converts to that repeating figure in feet. A nautical mile is about 15% longer than a statute mile of 5,280 feet — a difference that matters enormously in navigation.
Formula
feet = nautical miles × 6,076.11548556
nautical miles = feet ÷ 6,076.11548556
The nautical mile is defined as exactly 1,852 metres. The value in feet is 1,852 ÷ 0.3048, which does not terminate — so 6,076.12 is a rounding, not the definition.

What is a nautical mile in feet?
A nautical mile is exactly 1,852 metres, which is 6,076.11549 feet — about 796 feet longer than the 5,280-foot statute mile, or roughly 15% more. The two units have entirely separate origins. The nautical mile is derived from the Earth itself: it is one minute of arc of latitude, which is why 60 nautical miles equal one degree and why a latitude scale on a marine chart doubles as a distance ruler. The statute mile comes from the Roman mile and the English furlong, and has no relationship to the planet's dimensions. The 1,852-metre value was fixed at the 1929 International Hydrographic Conference. A knot is one nautical mile per hour, equal to 1.15078 mph or 1.68781 ft/s. The practical consequence is that 500 nautical miles is 575 statute miles — a 15% gap that becomes a serious error in any fuel or timing calculation.
Overview
About the nautical miles converter
The nautical mile is not a variant of the land mile — it comes from a different idea entirely. One nautical mile is one minute of latitude along a meridian, which makes it directly useful for navigation: a degree of latitude is 60 nautical miles anywhere on Earth.
That geographic origin is why it survives in aviation and at sea while almost every other imperial unit has been squeezed out. A chart position and a distance share the same scale, so no conversion is needed to work out how far apart two coordinates are.
The practical hazard is mixing it up with the statute mile. At 6,076.1 feet against 5,280, a nautical mile is 15.08% longer. On a 500-mile flight plan, treating one as the other puts you 75 miles out.
Method
How it's calculated
The nautical mile has been defined as exactly 1,852 metres since the 1929 International Hydrographic Conference. Converting to feet means dividing by 0.3048, the exact metres-per-foot figure, which gives 6,076.11548556… feet. The decimal continues, so any figure in feet is necessarily rounded.
To convert between nautical and statute miles, use the ratio of their lengths in feet: 6,076.11548556 ÷ 5,280 = 1.15078. So 1 nautical mile is 1.15078 statute miles, and 1 statute mile is 0.868976 nautical miles.
Going the other way, miles to feet does the reverse conversion. If you want a figure already worked out, conversion chart lists the common ones, and about & methodology documents every constant used here and where it comes from.
Examples
Worked examples
The arithmetic in full, using values people search for.
One nautical mile in feet
- 1Start from the definition: 1 nmi = 1,852 metres exactly.
- 2Divide by 0.3048 metres per foot.
- 3Round for display — the exact value does not terminate.
1 nautical mile = 6,076.1155 feet (commonly written 6,076.1 ft).
35,000 feet in nautical miles
- 1Start with the altitude: 35,000 ft.
- 2Divide by 6,076.1155.
- 3Compare with the statute-mile answer of 6.63.
35,000 ft = 5.76 nautical miles — noticeably less than the 6.63 statute miles.
A 100 nautical mile leg in statute miles
- 1Start with 100 nmi.
- 2Multiply by 1.15078.
- 3Read the statute-mile equivalent.
100 nautical miles = 115.08 statute miles, or 607,612 feet.
Key facts
What to remember
- 1 nautical mile = 1,852 metres exactly = 6,076.11548556 feet.
- 1 nautical mile = 1.15078 statute miles. A statute mile is 0.868976 nautical miles.
- One nautical mile equals one minute of latitude, so 1 degree of latitude is 60 nautical miles.
- A knot is one nautical mile per hour — 1.1508 mph or 1.6878 ft/s.
- Aviation reports altitude in feet but horizontal distance in nautical miles. The two units on your flight display are not the same mile.
- The UK used a slightly different Admiralty mile of 6,080 ft until 1970. Old charts may still carry it.
Accuracy
Assumptions and precision
Because the nautical mile is defined in metres, its value in feet never terminates. This converter carries the full 1,852 ÷ 0.3048 value internally and rounds only for display, so results stay correct even at ten decimal places.
The calculator never rounds internally. Rounding happens once, when a figure is drawn on screen, at the precision you choose with the slider — so converting a value and converting it back returns your original number exactly.
Applications
Who uses this conversion
The same arithmetic, for different reasons.
Sailors and navigators
Chart distances, latitude and speed in knots all share one scale. Converting to feet is only needed for depths, clearances and bridge heights.
Pilots and flight planners
A flight plan mixes feet for altitude with nautical miles for distance. Treating a nautical mile as a statute mile is a 15% error in every leg.
Engineers and surveyors
Marine and offshore work specifies distances in nautical miles but drawings in feet. The conversion appears on every set of plans.
Students of geography
The nautical mile is the clearest example of a unit derived from the shape of the Earth rather than from a physical artefact.
