The inch (in) is a small unit of length in the imperial and US customary systems, commonly used in the United States and the United Kingdom. It is often used to measure screen sizes, human height, and small objects. One inch is exactly 1/12 of a foot or 2.54 centimeters.

The mile (mi) is a much larger unit of length, primarily used for measuring long distances such as road lengths, running tracks, and geographic distances. One mile is equal to 5,280 feet or 63,360 inches.
To convert inches to miles, use this formula:
miles = inches ÷ 63,360
For example, if you want to convert 100,000 inches to miles:
100,000 ÷ 63,360 = 1.578 mi
This means that 100,000 inches is approximately 1.58 miles.

How Inches and Miles Helped Build the Transcontinental Railroad
During the 1860s, the United States was undergoing a major transformation with the construction of the Transcontinental Railroad. The goal was to connect the East Coast to the West Coast, reducing travel time across the country from months to just a few days.
One of the biggest challenges was ensuring that the tracks from different railroad companies matched perfectly. Engineers had to work with both imperial and metric measurements, often converting inches into miles to maintain precision over thousands of miles of track. A small miscalculation of even a few inches could have caused serious alignment issues, delaying the project or even causing accidents.
When the final golden spike was driven at Promontory Summit, Utah, in 1869, the railroad successfully united the nation—thanks in part to precise conversions between inches and miles.
