The Ratio Between Feet and Miles

Visualising the relationship between feet and miles makes it easier to convert between the two. Feet are used to establish the baseline ruler and the miles ruler is sized in relation to that baseline.

How to convert feet to miles (ft to mi)

Converting feet to miles involves dividing the number of feet by the number of feet in a mile. Here's the conversion factor and the process: 1 mile is equal to 5280 feet. To convert feet to miles, you divide the number of feet by 5280. The feet to miles conversion formula is: mi = ft ÷ 5280.

Example Conversion

Let's take a look at an example. The step-by-step process to convert 2640 feet to miles is:

Understand the conversion formula: mi = ft ÷ 5280
Substitute the required value. In this case we substitute 2640 for ft so the formula becomes: mi = 2640 ÷ 5280
Calculate the result using the provided values. In our example the result is: 2640 ÷ 5280 = 0.5 mi

In summary, 2640 feet is equal to 0.5 miles.

Converting miles to feet

In order to convert the other way around i.e. miles to feet, you would use the following formula: ft = mi × 5280. To convert miles to feet first substitute the mile value into the above formula, and then execute the calculation. If we wanted to calculate 1 mile in feet we follow these steps:

ft = mi × 5280

ft = 1 × 5280

ft = 5280

Or in other words, 1 mile is equal to 5280 feet.

Conversion Unit Definitions

What is a Foot?

The foot (pl. feet), standard symbol: ft, is a unit of length in the British imperial and United States customary systems of measurement. The prime symbol, ′, is a customarily used alternative symbol. Since the International Yard and Pound Agreement of 1959, one foot is defined as 0.3048 meters exactly. In both customary and imperial units, one foot comprises 12 inches and one yard comprises three feet.

Historically the "foot" was a part of many local systems of units, including the Greek, Roman, Chinese, French, and English systems. It varied in length from country to country, from city to city, and sometimes from trade to trade. Its length was usually between 250 mm and 335 mm and was generally, but not always, subdivided into 12 inches or 16 digits.

The United States is the only industrialized nation that uses the international foot in preference to the meter in its commercial, engineering, and standards activities. The foot is legally recognized in the United Kingdom; road signs must use imperial units (however, distances on road signs are always marked in miles or yards, not feet), while its usage is widespread among the British public as a measurement of height.

Here are some more details about the foot:

Historical Context: The foot has been used as a unit of measurement for thousands of years and has roots in various ancient civilizations. It was originally based on the length of a human foot, but over time, standardized units were developed to ensure consistency.
Imperial and US Customary Systems: The foot is a fundamental unit in both the Imperial system and the United States Customary system. These systems of measurement are closely related and share many common units. The foot is divided into 12 inches and is further subdivided into smaller units such as the inch, half-inch, quarter-inch, etc.
Length Conversion: As mentioned earlier, one foot is equal to 12 inches or approximately 30.48 centimeters. Conversely, one inch is equal to 1/12th of a foot.
Symbol: The symbol for foot is a single prime ('). For example, a measurement of 5 feet would be written as 5'.
Usage: The foot is commonly used in various applications, including construction, architecture, interior design, surveying, and sports. It is often used to measure heights, distances, room dimensions, and other similar quantities.
Subdivisions: The foot can be divided into smaller units to measure finer lengths. Apart from the inch, mentioned earlier, there are also other subdivisions used in specific contexts. For example, in surveying, a foot can be divided into tenths or hundredths for precise measurements.
International Usage: While the metric system (based on the meter) is the predominant system of measurement used worldwide, the foot is still used in certain countries, such as the United States and the United Kingdom, especially in everyday contexts. However, it's worth noting that in scientific, technical, and international contexts, the meter is typically used for consistency and compatibility.

What is a Mile?

The mile is a unit of length primarily used in the United States and a few other countries that have historical ties to the British Empire. It is defined as 5,280 feet or approximately 1.609 kilometers. The mile is commonly used to measure longer distances, especially in transportation, sports, and everyday contexts in countries that have not fully adopted the metric system.

Here are some more details about the mile:

Historical Context: The mile has a long history and can be traced back to ancient Roman measurements. It was standardized and defined differently over time, but the modern definition was established in the 16th century.
Imperial and US Customary Systems: The mile is a fundamental unit of length in both the Imperial system (used in the UK) and the United States Customary system. These systems of measurement are closely related and share many common units. The mile is divided into feet, and each foot is further divided into inches.
Length Conversion: As mentioned earlier, one mile is equal to 5,280 feet or approximately 1.609 kilometers. Conversely, one foot is equal to 1/5,280th of a mile, and one inch is equal to 1/63,360th of a mile.
Common Uses: The mile is often used to measure longer distances, especially in transportation, sports events (such as marathons), and everyday contexts in countries that have not fully transitioned to the metric system. It is commonly employed in fields such as road signs, aviation, maritime navigation, and athletic competitions.
Symbol: The symbol for mile is "mi". For example, a measurement of 5 miles would be written as 5 mi.
Subdivisions: The mile can be divided into smaller units to measure finer lengths. The most common subdivision used in practical contexts is the yard, where one mile is equal to 1,760 yards. In some specific applications, even smaller subdivisions like the furlong or rod may be used.
International Usage: While the metric system (based on the meter) is the predominant system of measurement used worldwide, the mile is still used in certain countries, especially the United States and the United Kingdom, in everyday contexts. However, in scientific, technical, and international contexts, the kilometer is typically used for consistency and compatibility.
