## How many nautical miles (nmi) are in 1 kilometer (km)? What is the formula for how to convert nautical miles to kilometers (nmi to km)?

**1 nautical mile (nmi) = 1.852 kilometers (km)**

So we can say that there is 1.852 kilometers in 1 nautical mile.

This means that the multiplication conversion factor to convert a quantity expressed in a nautical mile unit of measurement to an equivalent quantity expressed in a kilometers unit of measurement is 1.852.

Inversely (or reciprocally),

**1 kilometer (km) = 0.53995680345572 nautical mile (nmi)**

So we can say that there is 0.53995680345572 nautical mile in 1 kilometer.

This means that the division conversion factor to convert a quantity expressed in a nautical mile unit of measurement to an equivalent quantity expressed in a kilometer unit of measurement is 0.53995680345572.

Knowing this inverse mathematical relationship between the two conversion factors and their reciprocal operations, we can derive two formulas to calculate and convert a quantity of length expressed in nautical miles to an equivalent quantity of length expressed in kilometers (nmi to km). Both formulas will yield the same result. The formulas are:

km = nmi × 1.852→ This is the formula based on the multiplication conversion factor.

and

km = nmi ÷ 0.53995680345572→ This is the formula based on the division conversion factor.

For example, if you have a length of 150 nautical miles that you want to convert to kilometers, you would use either of the two formulas as follows:

km = 150 nmi × 1.852 = 277.8 km

km = 150 nmi ÷ 0.53995680345572 = 277.8 km

So, the result is the same using either formula, which is 277.8 kilometers.

## What is a nautical mile (nmi)?

**Definition of nautical mile:** A nautical mile is a unit of length used primarily in maritime and aviation contexts for measuring distances over water or air. It is based on the Earth’s circumference and is defined as one minute of latitude along any meridian. It is approximately equal to 1,852 meters or about 1.15078 miles.

The nautical mile technically not part of the U.S. customary, imperial or metric systems of measurement. Therefore the nautical mile is considered as a specialized unit of measurement distinct from other systems of measurement, used specifically for maritime and aviation navigational purposes.

The abbreviation for nautical mile is **nmi**.

## What is a kilometer (km)?

**Definition of kilometer:** A kilometer is a unit of length in the International System of Units (SI), commonly known as the metric system, equal to one thousand meters (10^3 m). It is commonly used for longer distances, such as races, road distances and geographical features.

The abbreviation for kilometer is **km**. The single Unicode character **㎞** (U+339E) represents the 2-character Latin abbreviation for kilometer. The Windows Alt code for this character **㎞** is Alt + 13214.
