Convert Centimeters to Nautical miles

1 centimeter is 0.0000054 nmi. One centimeter is exactly 0.00000539956803456 nautical miles.

One centimeter is 5.3996 × 10^-6 nautical miles. To convert centimeters to nautical miles, multiply by 5.3996 × 10^-6; to go the other way, divide by 5.3996 × 10^-6 or multiply by 185200. 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. One hundredth of a meter, and the unit most of the world states height in.

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: centimetres to nautical miles 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 centimeters to nautical miles? The converter and the working

  1. 1.Take the measurement in centimeters.
  2. 2.Multiply by 5.3996 × 10^-6 — that is how many nautical miles fit in one centimeter.
  3. 3.To go back the other way, divide by 5.3996 × 10^-6, or multiply by 185200.

Worked example: 25 centimeters to nautical miles

Formula
cm × 5.3996 × 10^-6 = nmi
Arithmetic
25 × 5.3996 × 10^-6 = 0.000135 nmi
Answer
25 cm = 0.000135 nmi

The factor is rounded for display; the figure above is computed from the full value.

What is a centimeter?

One hundredth of a meter, and the unit most of the world states height in.

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 centimeter?

One centimeter is 5.3996 × 10^-6 nautical miles. Going the other way, one nautical mile is 185200 centimeters. 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.
