The correct answer is 1.853 (which is the closest approximation to the internationally standardized value of $1.852$ km).A nautical mile is a unit of measurement used in air, marine, and space navigation. Unlike the "statute" mile used on land, the nautical mile is derived from the Earth's geometry.
Historically, a nautical mile was defined as one minute ($1'$) of latitude along any meridian.Since a full circle has 360 degrees and each degree consists of 60 minutes, the Earth's circumference is roughly $360 \times 60 = 21,600$ nautical miles
In 1929, the international community agreed to standardize the measurement. The International Nautical Mile is now officially defined as exactly 1,852 meters.+11 Nautical Mile = $1.852$ Kilometers1 Nautical Mile = $1.1508$ Statute (Land) Miles1 Nautical Mile = $6,076.1$ Feet
Nautical miles are used because they correspond directly to the coordinate system on maps. If a sailor or pilot moves one nautical mile due North or South, they have traveled exactly one minute of latitude. This makes calculating distances using a map's scale extremely efficient without needing complex conversions.
