Convert Nautical miles to Centimeters

1 nautical mile is 185,200 cm. One nautical mile is exactly 185200 centimeters.

One nautical mile is 185200 centimeters. To convert nautical miles to centimeters, multiply by 185200; to go the other way, divide by 185200 or multiply by 5.3996 × 10^-6. 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 centimetres 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 centimeters? The converter and the working

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

Worked example: 25 nautical miles to centimeters

Formula
nmi × 185200 = cm
Arithmetic
25 × 185200 = 4,630,000 cm
Answer
25 nmi = 4,630,000 cm

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 centimeter?

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

How many centimeters are in a nautical mile?

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