Convert Yards to Nautical miles
1 yard is 0.0004937 nmi. One yard is exactly 0.00049373650108 nautical miles.
One yard is 4.9374 × 10^-4 nautical miles. To convert yards to nautical miles, multiply by 4.9374 × 10^-4; to go the other way, divide by 4.9374 × 10^-4 or multiply by 2025.3718. 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. Three feet, or exactly 0.9144 meters.

Factors are entered by hand from NIST rather than derived from a units library, so the ones that terminate are exact rather than rounded.
How do you convert yards to nautical miles? The converter and the working
- 1.Take the measurement in yards.
- 2.Multiply by 4.9374 × 10^-4 — that is how many nautical miles fit in one yard.
- 3.To go back the other way, divide by 4.9374 × 10^-4, or multiply by 2025.3718.
Worked example: 25 yards to nautical miles
- Formula
- yd × 4.9374 × 10^-4 = nmi
- Arithmetic
- 25 × 4.9374 × 10^-4 = 0.01 nmi
- Answer
- 25 yd = 0.01 nmi
The factor is rounded for display; the figure above is computed from the full value.

What is a yard?
Three feet, or exactly 0.9144 meters. Concrete and fabric are both sold by it.
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 yard?
One yard is 4.9374 × 10^-4 nautical miles. Going the other way, one nautical mile is 2025.3718 yards. 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.
