How to convert1 nautical mile (nmi) = 1852 meter (m). Nautical Mile (nmi) is a unit of Length used in Standard system. Meter (m) is a unit of Length used in Metric system. Nautical Mile: A Unit of LengthA nautical mile is a unit of length that is used in air, marine, and space navigation, and for the definition of territorial waters. It is based on the Earth’s longitude and latitude coordinates, and is equal to one minute of arc along a meridian. In this article, we will explore the definition, history, uses, and conversions of the nautical mile. Definition of the Nautical MileThe nautical mile is defined as exactly 1,852 metres (6,076 feet; 1.151 miles) by the International Hydrographic Organization (IHO) since 1929. This definition is based on the length of one minute of arc along a great circle of a sphere having the same surface area as the Clarke 1866 ellipsoid, which approximates the shape of the Earth. The nautical mile is not an SI unit, but it is accepted for use with the SI by the International Committee for Weights and Measures. The derived unit of speed is the knot, which is one nautical mile per hour. History of the Nautical MileThe concept of the nautical mile dates back to ancient times, when navigators used the stars and angles to measure distances at sea. The word mile comes from the Latin phrase mille passus, meaning a thousand paces. The nautical mile was originally defined as the length on the Earth’s surface of one minute of arc along a meridian (northsouth line of longitude). However, this definition varied depending on the latitude and the shape of the Earth assumed by different countries. For example, France defined a nautical mile as one tenmillionth of a quarter meridian using the original 1791 definition of the metre.The United States and the United Kingdom used an average arcminute based on the Clarke 1866 ellipsoid. In order to standardize the nautical mile, the IHO adopted the current definition in 1929, which was later endorsed by other international organizations such as the International Civil Aviation Organization (ICAO) and the International Maritime Organization (IMO). The United States adopted the international nautical mile in 1954 and the United Kingdom in 1970. Where Nautical Mile is UsedThe nautical mile is widely used in navigation, especially for maritime and aviation purposes. It is convenient to use because it corresponds to one minute of latitude, which can be easily measured with a sextant or a GPS device. It also allows for simple calculations of distances along great circles, which are the shortest routes between two points on a sphere. Some examples of where nautical mile is used are:
How to Convert Nautical MileThe nautical mile can be converted to other units of length using simple multiplication or division by a conversion factor. Here are some common conversion factors:
For example, to convert 10 nautical miles to kilometres, we multiply by 1.852: 10 NM × 1.852 = 18.52 km To convert 50 kilometres to nautical miles, we divide by 1.852: 50 km ÷ 1.852 = 27 NM Example Conversions of Nautical Mile to Other UnitsHere are some example conversions of nautical mile to other units:
Meter  Unit of Distance / LengthUnit Symbol / Abbreviation: m Where the unit used in the World: The meter is used as a unit to measure medium distances or lengths. Definition of the Unit: The meter (metre in UK spelling) is a unit of length/distance in the metric system (SI Unit system) equivalent to the length of the path travelled by light during a time interval of 1/299,792,458 of a second (in vacuum, defined since 1983). 1 m is equivalent to 3.28084 ft or 0.000621371 miles. History of the Unit: As a result of the French Revolution in 1789, the old units of measure that were associated with the monarchy were replaced by the new units. The new unit of length was introduced which became known as the meter. In 1795 the meter was defined as 1/10,000,000 part of the quarter of a meridian, passing through Paris. The meter gained popularity in continental Europe during the nineteenth century, particularly in scientific field, and was officially adopted as an international measurement unit in 1875. In 1960 the meter was defined as 1,650,763.73 wavelengths of light from a specified transition in krypton86. In 1983 the final definition of meter was accepted as length of the path travelled by light in a vacuum in 1/299,792,458 of a second. Where it's used: The meter is commonly used in different trades and industries (for examle in machinery manufacturing), on road signs to indicate vehicle hight limits, the distance to short travel to a given location (for example in automotive GPS navigation voice prompts), on maps to indicate small scale, for vehicle, vessels and aircragt dimensions in industry and trade. It is also the most popular unit for describing the retail estate distances and measurements (room sizes, floor measurements and so on). Equivalents in other units and scales:
1 m is equivalent to 3.28084 ft or 1.09361 yd. Español Russian Français
