Distance units
Understanding distance conversions is an essential skill in both everyday life and professional activities. Distances can be expressed in multiple units, two of which are miles (mi) and nautical miles (nmi). The “Miles to Feet Converter” tool allows users to effortlessly convert these distance units into feet, providing insights into a range of applications from navigation and travel to geographical measurements.
Definition of a mile (mi)
A mile is a unit of length commonly used in the United States for measuring distances. It is equal to 5 280 feet or approximately 1 609.34 meters. Historically, the mile originated from the Roman mile, known as the “mille passuum,” which meant 1,000 paces.
Definition of a nautical mile (nmi)
A nautical mile is primarily used in maritime and aviation contexts. It is based on the circumference of the Earth and is equal to one minute of latitude. One nautical mile equals 6,076.1 feet or approximately 1,852 meters. The nautical mile is increasingly preferred in navigation for its convenience in simplifying chart and course plotting.
Definition of feet (ft)
Feet is a unit of length in the imperial system of measurement. One foot is equal to 0.3048 meters.
Formulas
Let’s convert miles to feet and vice versa using the following formulas.
Converting miles to feet. To convert miles to feet, multiply the number of miles by 5,280:
Converting nautical miles to feet. To convert nautical miles to feet, multiply the number of nautical miles by 6,076.1:
Formula for converting feet to miles. To convert feet to miles, divide the number of feet by 5,280:
Formula for converting feet to nautical miles. To convert feet to nautical miles, divide the number of feet by 6 076.1:
Useful examples
Example 1: Converting 3 mi to ft
Use the formula: ft. So, 3 miles is equivalent to 15,840 feet.
Example 2: Converting 2 nnmi to ft
Given: 2 nautical miles, calculation: ft. Thus, 2 nautical miles equals 12,152.2 feet.
Example 3: How many feet are in 0.8 nmi?
Substitute the values into the formula: ft. So, 0.8 nautical miles convert to 4,860.88 feet.
Example 4: Convert miles to feet
Use the reverse formula: feet. Thus, 10 miles is 52,800 feet.

Why are nautical miles used instead of regular miles in navigation?
Nautical miles are based on the Earth’s circumference, providing a more natural fit for longitude and latitude calculations, which aids in accurate navigation.
Are miles and nautical miles used interchangeably?
No, miles (usually statute miles) are used mainly for terrestrial distances, while nautical miles are used for nautical and aerial navigation because they align with lines of latitude and longitude.
