How many Land Miles equal one Nautical Mile?

Approximately 1.15 land miles equal one nautical mile, according to the definition of the two metrics. An approximation with a higher precision is that 1.150779448 miles equal 1 nm. The standardized symbols for the two units are mi and M, but "m" is used for miles in a few countries, which might lead to confusion with the meter, while "nm" and "nmi" are also used to refer to nautical miles in some professional circles.

Difference between Nautical Miles and Land Miles

As the names suggest, the main difference between a land mile and a nautical mile is what they are used to measure. The land mile is mostly used for expressing the distance between points on land surface, while nautical miles are mostly used for distances at sea, or through historical reasons: in the air. Thus, land navigation happens in land miles, while marine and air navigation happens in nautical miles.

Other than that, the metrics are mostly identical, except for their slight difference in magnitude, which is due to the fact that historically, the nautical mile was defined as one minute of latitude, thus equivalent to one sixtieth of a degree. Both units are mostly being replaced by meters and kilometers in scientific and engineering uses, but remain widely used in everyday life in a couple of countries, most notably the United States.

How to convert Nautical Miles to Miles

To convert from nautical miles to miles, multiply the measurement in nm by 1.150779448 to get the corresponding measurement in miles. Usually using a calculator or an online converter such as this one would be convenient due to the fraction part, especially if accuracy is of the essence.
