How It Works

This miles converter uses internationally standardized conversion factors to provide exact distance conversions between various units of length.

Conversion Method

All conversions use meters as the base unit. The conversion process follows these steps:

Step 1: Convert input to meters: \( m = x \times f_{from} \)

Step 2: Convert meters to target unit: \( y = \frac{m}{f_{to}} \)

Where \( x \) is the input value, \( f_{from} \) is the conversion factor from the source unit to meters, and \( f_{to} \) is the conversion factor from meters to the target unit.

Exact Conversion Factors

Standard conversion factors (based on international definitions):

\( 1\,\text{mi} = 1609.344\,\text{m} \) (international mile)

\( 1\,\text{nmi} = 1852\,\text{m} \) (nautical mile)

\( 1\,\text{km} = 1000\,\text{m} \)

\( 1\,\text{yd} = 0.9144\,\text{m} \)

\( 1\,\text{ft} = 0.3048\,\text{m} \)

\( 1\,\text{in} = 0.0254\,\text{m} \)

\( 1\,\text{fur} = 201.168\,\text{m} \) (furlong)

Example Calculation

To convert 5 miles to kilometers:

\( \text{meters} = 5 \times 1609.344 = 8046.72\,\text{m} \)

\( \text{kilometers} = \frac{8046.72}{1000} = 8.04672\,\text{km} \)

Common Uses

Running & Racing

  • 5K race: 3.107 miles
  • 10K race: 6.214 miles
  • Half marathon: 13.1 miles (21.0975 km)
  • Full marathon: 26.2 miles (42.195 km)
  • Runners often need to convert between miles and kilometers for training plans and race distances.

Road Trips & Travel

  • Converting highway distances when traveling between countries using different measurement systems
  • Understanding fuel efficiency (miles per gallon vs. kilometers per liter)
  • Planning international road trips across borders
  • Reading road signs in different countries

Aviation & Maritime Navigation

  • Nautical miles: Used in aviation and maritime navigation (1 nmi = 1.15078 mi)
  • Flight distances and aircraft range calculations
  • Ship voyage planning and fuel consumption
  • One nautical mile equals one minute of latitude, making it practical for navigation

Frequently Asked Questions

How do I convert miles to kilometers?
To convert miles to kilometers, multiply the number of miles by 1.609344. For example, 5 miles × 1.609344 = 8.04672 kilometers. This is the exact conversion factor defined by international standards.
How many kilometers are in one mile?
One mile equals exactly 1.609344 kilometers. This is the internationally standardized conversion factor based on the definition of the international mile as 1,760 yards or 5,280 feet, where one yard equals 0.9144 meters.
How do I convert miles to meters?
Multiply miles by 1,609.344 to get meters. For example, 1 mile = 1,609.344 meters. For quick estimation, remember that 1 mile is approximately 1,600 meters.
What is a nautical mile and how does it differ from a regular mile?
A nautical mile (1,852 meters) is longer than a statute mile (1,609.344 meters). Nautical miles are used in aviation and maritime navigation because one nautical mile equals one minute of latitude, making it practical for navigation on Earth's surface. One nautical mile equals approximately 1.15078 statute miles.
What is the difference between a mile and a statute mile?
The terms "mile" and "statute mile" typically refer to the same unit: the international mile of 5,280 feet or 1,609.344 meters. The term "statute mile" is sometimes used to distinguish it from the nautical mile. The older U.S. survey mile differs by only about 3mm and is rarely used today.
How many feet are in a mile?
There are exactly 5,280 feet in one mile. This is derived from the definition that 1 mile = 1,760 yards, and 1 yard = 3 feet, so 1,760 × 3 = 5,280 feet.
How far is a marathon in miles?
A marathon is 26.2 miles, which equals 42.195 kilometers. A half marathon is 13.1 miles or 21.0975 kilometers. These distances are standardized for official racing events worldwide.
Can I convert negative distances in miles?
While the calculator allows negative inputs for mathematical purposes, distance in physical terms is always non-negative. Negative values might be used in certain coordinate systems or mathematical contexts, but typical distance conversions use positive values.
How do I adjust decimal precision in conversions?
Use the precision slider in the "Optional: precision & advanced units" section to set decimal places from 0 to 10. For most practical purposes, 2-3 decimal places are sufficient. Scientific applications may require higher precision.
Can I export the conversion table to Excel or CSV?
Yes! After generating a conversion table (common values, step table, or custom list), click the "Export as CSV" button. The CSV file can be opened in Excel, Google Sheets, or any spreadsheet application for further analysis or record-keeping.
