Convert Feet to Nautical miles
1 foot is 0.0001646 nmi. One foot is exactly 0.000164578833693 nautical miles.
One foot is 1.6458 × 10^-4 nautical miles. To convert feet to nautical miles, multiply by 1.6458 × 10^-4; to go the other way, divide by 1.6458 × 10^-4 or multiply by 6076.1155. The relation is exact but the figure is not: it is a rounding of a number that does not terminate, and it follows from NIST. Twelve inches, or exactly 0.3048 meters.

How do you convert feet to nautical miles? The converter and the working
- 1.Take the measurement in feet.
- 2.Multiply by 1.6458 × 10^-4 — that is how many nautical miles fit in one foot.
- 3.To go back the other way, divide by 1.6458 × 10^-4, or multiply by 6076.1155.
Worked example: 25 feet to nautical miles
- Formula
- ft × 1.6458 × 10^-4 = nmi
- Arithmetic
- 25 × 1.6458 × 10^-4 = 0.004114 nmi
- Answer
- 25 ft = 0.004114 nmi
The factor is rounded for display; the figure above is computed from the full value.

What is a foot?
Twelve inches, or exactly 0.3048 meters. Still the working unit of US construction.
What is a nautical mile?
Exactly 1,852 meters by international agreement since 1929, chosen because it is one minute of latitude — which is why a chart, a speed in knots and a position in degrees all use the same arithmetic.
How many nautical miles are in a foot?
One foot is 1.6458 × 10^-4 nautical miles. Going the other way, one nautical mile is 6076.1155 feet. Both figures come from the same defined relation rather than from a measurement, which is why they are the same today as they were in 1959.
Every length unit here
The whole group — 13 units with their symbols and the size of each one in meters — is on the conversion index, along with every pair it makes. The table above already gives each of them relative to a foot.
