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

**1 mile (mi) = 0.86897624190065 nautical mile (nmi)**

So we can say that there is 0.86897624190065 nautical mile in 1 mile.

This means that the multiplication conversion factor to convert a quantity expressed in a mile unit of measurement to an equivalent quantity expressed in a nautical mile unit of measurement is 0.86897624190065.

Inversely (or reciprocally),

**1 nautical mile (nmi) = 1.1507794480235 miles (mi)**

So we can say that there is 1.1507794480235 miles in 1 nautical mile.

This means that the division conversion factor to convert a quantity expressed in a mile unit of measurement to an equivalent quantity expressed in a nautical mile unit of measurement is 1.1507794480235.

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 miles to an equivalent quantity of length expressed in nautical miles (mi to nmi). Both formulas will yield the same result. The formulas are:

nmi = mi × 0.86897624190065→ This is the formula based on the multiplication conversion factor.

and

nmi = mi ÷ 1.1507794480235→ This is the formula based on the division conversion factor.

For example, if you have a length of 450 miles that you want to convert to nautical miles, you would use either of the two formulas as follows:

nmi = 450 mi × 0.86897624190065 = 391.039308855 nmi

nmi = 450 mi ÷ 1.1507794480235 = 391.039308855 nmi

So, the result is the same using either formula, which is 391.039308855 nautical miles.

## What is a mile (mi)?

**Definition of mile:** A mile (formally known as statute mile) is an imperial and US customary unit of length equivalent to 1,760 yards or 1.609 kilometers. It is commonly used in the United States and the United Kingdom for measuring longer distances, especially on roads and highways. The abbreviation for mile is **mi**.

## 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**.
