Distances on land are usually measured in miles (mi), while distances across seas and skies are measured in nautical miles (nmi). This can create confusion when comparing different measurements. The Nautical Mile to Mile Calculator (nmi to mi) helps you instantly convert between these two important units with complete accuracy.
What is a Nautical Mile?
- A nautical mile (nmi) is a unit of measurement based on the Earth’s circumference.
- 1 nautical mile = 1,852 meters.
- Used globally in aviation, maritime, and navigation charts.
- It corresponds to one minute of latitude.
What is a Mile?
- A mile (mi), often called a statute mile, is commonly used on land.
- 1 mile = 1,609.34 meters.
- Widely used in the United States, United Kingdom, and countries where the imperial system is common.
Formula for Nautical Mile to Mile Conversion
Since:
- 1 nmi = 1.852 km
- 1 mile = 1.60934 km
We calculate:
1 nmi = 1.15078 miles
Formula:
Miles = Nautical Miles × 1.15078
How to Use the Nautical Mile to Mile Calculator
- Enter the value in nautical miles (nmi).
- Press the Convert button.
- Instantly get the result in miles (mi).
Example:
Convert 10 nmi to miles:
10 × 1.15078 = 11.51 mi
Examples of Nautical Mile to Mile Conversion
- 1 nmi = 1.15078 mi
- 5 nmi = 5.754 mi
- 10 nmi = 11.51 mi
- 20 nmi = 23.02 mi
- 50 nmi = 57.54 mi
- 100 nmi = 115.08 mi
- 500 nmi = 575.39 mi
Worked Example:
Convert 250 nautical miles to miles:
250 × 1.15078 = 287.7 mi
