Convert Nautical miles to Thou
1 nautical mile is 72,913,385.83 thou. One nautical mile is exactly 72913385.8268 thou.
One nautical mile is 7.2913 × 10^+7 thou. To convert nautical miles to thou, multiply by 7.2913 × 10^+7; to go the other way, divide by 7.2913 × 10^+7 or multiply by 1.3715 × 10^-8. 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.

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 nautical miles to thou? The converter and the working
- 1.Take the measurement in nautical miles.
- 2.Multiply by 7.2913 × 10^+7 — that is how many thou fit in one nautical mile.
- 3.To go back the other way, divide by 7.2913 × 10^+7, or multiply by 1.3715 × 10^-8.
Worked example: 25 nautical miles to thou
- Formula
- nmi × 7.2913 × 10^+7 = thou
- Arithmetic
- 25 × 7.2913 × 10^+7 = 1,822,834,645.67 thou
- Answer
- 25 nmi = 1,822,834,645.67 thou
The factor is rounded for display; the figure above is computed from the full value.

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 thou?
A thousandth of an inch, exactly 25.4 micrometers, and called a mil in American workshops — the same word the metric world uses for a millimeter, which is why a drawing marked "5 mil" is worth checking twice.
How many thou are in a nautical mile?
One nautical mile is 7.2913 × 10^+7 thou. Going the other way, one thou is 1.3715 × 10^-8 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.
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 nautical mile.
