The Ratio Between Miles and Inches

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

How to convert miles to inches (mi to in)

The formula for converting miles to inches is: in = mi × 63360. To calculate the mile value in inches first substitute the mile value into the preceding formula, and then perform the calculation. If we wanted to calculate 1 mile in inches we follow these steps:

in = mi × 63360

in = 1 × 63360

in = 63360

In other words, 1 mile is equal to 63360 inches.


Example Conversion

Let's take a look at an example. The step-by-step process to convert 9 miles to inches is:

  1. Understand the conversion formula: in = mi × 63360
  2. Substitute the required value. In this case we substitute 9 for mi so the formula becomes: in = 9 × 63360
  3. Calculate the result using the provided values. In our example the result is: 9 × 63360 = 570240 in

In summary, 9 miles is equal to 570240 inches.


Converting inches to miles

To convert inches to miles, you need to use the conversion factor that represents how many inches are in a mile. There are 63,360 inches in a mile. Therefore, the formula to convert inches to miles (in to mi) is: mi = in ÷ 63360.For example, if you have 126,720 inches, the conversion to miles would be: Miles = 126,720 inches ÷ 63,360 inches per mile ​= 2 miles. So, 126,720 inches is equal to 2 miles.

Conversion Unit Definitions

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:
  1. 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.

  2. 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.

  3. 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.

  4. 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.

  5. Symbol: The symbol for mile is "mi". For example, a measurement of 5 miles would be written as 5 mi.

  6. 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.

  7. 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.

What is a Inch?

The inch (symbol: in or ″) is a unit of length in the British imperial and the United States customary systems of measurement. It is equal to 1/36 yard or 1/12 of a foot. Derived from the Roman uncia ("twelfth"), the word inch is also sometimes used to translate similar units in other measurement systems, usually understood as deriving from the width of the human thumb.
Standards for the exact length of an inch have varied in the past, but since the adoption of the international yard during the 1950s and 1960s the inch has been based on the metric system and defined as exactly 25.4 mm.
The inch is a commonly used customary unit of length in the United States, Canada, and the United Kingdom. It is also used in Japan for electronic parts, especially display screens. In most of continental Europe, the inch is also used informally as a measure for display screens. For the United Kingdom, guidance on public sector use states that, since 1 October 1995, without time limit, the inch (along with the foot) is to be used as a primary unit for road signs and related measurements of distance (with the possible exception of clearance heights and widths) and may continue to be used as a secondary or supplementary indication following a metric measurement for other purposes.

Here are some additional details about the inch:

  1. Origin: The inch has its roots in the ancient Roman measurement system. The word "inch" is derived from the Latin word "uncia," which means one-twelfth part.

  2. Imperial and US Customary Systems: The inch is a fundamental unit in both the Imperial system and the United States Customary system. These systems of measurement are primarily used in the United States and other countries that have historical ties to the British Empire.

  3. Length Conversion: As mentioned earlier, one inch is equal to exactly 1/12th of a foot. In the metric system, it is approximately equal to 2.54 centimeters. Conversely, one foot is equal to 12 inches.

  4. Subdivisions: The inch can be further divided into smaller units to measure even finer lengths. Common subdivisions include:

    • Half-inch (1/2 inch): Equal to 0.5 inches or approximately 1.27 centimeters.
    • Quarter-inch (1/4 inch): Equal to 0.25 inches or approximately 0.635 centimeters.
    • Eighth-inch (1/8 inch): Equal to 0.125 inches or approximately 0.318 centimeters.
    • Sixteenth-inch (1/16 inch): Equal to 0.0625 inches or approximately 0.159 centimeters.
    • Thirty-second inch (1/32 inch): Equal to 0.03125 inches or approximately 0.079 centimeters.
  5. Common Uses: The inch is commonly used to measure various objects, particularly in fields like construction, engineering, manufacturing, and carpentry. It is often used to measure dimensions of building materials, tools, furniture, and other everyday items.

  6. Symbol: The symbol for inch is a double prime ("). For example, a measurement of 5 inches would be written as 5".

  7. International Usage: While the metric system (based on the meter) is widely adopted worldwide, the inch is still used in certain countries, such as the United States, Canada, and the United Kingdom. However, it is worth noting that many industries and scientific disciplines have transitioned to using metric measurements for international consistency.
