Convert Nautical miles to Meters
1 nautical mile is 1,852 m. One nautical mile is exactly 1852 meters.
One nautical mile is 1852 meters. To convert nautical miles to meters, multiply by 1852; to go the other way, divide by 1852 or multiply by 5.3996 × 10^-4. The factor is exact rather than rounded: it follows from NIST.

Factors are entered by hand from NIST rather than derived from a units library, so the ones that terminate are exact rather than rounded.
The same converter answers this pair however it is written: nautical miles to metres is the British spelling of the same units — the metre and the litre are spelled that way outside the United States and the quantity does not change.
How do you convert nautical miles to meters? The converter and the working
- 1.Take the measurement in nautical miles.
- 2.Multiply by 1852 — that is how many meters fit in one nautical mile.
- 3.To go back the other way, divide by 1852, or multiply by 5.3996 × 10^-4.
Worked example: 25 nautical miles to meters
- Formula
- nmi × 1852 = m
- Arithmetic
- 25 × 1852 = 46,300 m
- Answer
- 25 nmi = 46,300 m
The factor is exact, so this figure is exact too — only the display is rounded.

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.
What is a meter?
The SI base unit, defined since 1983 by the distance light travels in 1/299,792,458 of a second.
How many meters are in a nautical mile?
One nautical mile is 1852 meters, exactly. Going the other way, one meter is 5.3996 × 10^-4 nautical miles. 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.
