Convert astronomical units to miles or kilometers, or enter a distance in miles or kilometers to find the equivalent AU for space distance conversions.

Enter a distance, choose its unit, and select the unit for your result. Miles means international miles.

AU to Miles Formula

The following formula is used to convert astronomical units (AU) to miles.

M = AU × CF

Variables:

  • M is the distance in miles
  • AU is the distance in astronomical units
  • CF is the conversion factor (1 AU ≈ 92,955,807.273026 miles)

To convert astronomical units to miles, multiply the number of astronomical units by the conversion factor.

What is an Astronomical Unit?

An astronomical unit (AU) is a unit of length used in astronomy to measure distances within our solar system. It is approximately equal to the average distance between the Earth and the Sun, which is about 92,955,807.273026 miles. The astronomical unit provides a convenient way to express and relate distances of celestial objects in a manner that is easier to comprehend than using miles or kilometers.

How to Calculate Distance in Miles from AU?

The following steps outline how to calculate the distance in miles from astronomical units.

  1. First, determine the distance in astronomical units (AU).
  2. Next, use the conversion factor (1 AU ≈ 92,955,807.273026 miles).
  3. Multiply the distance in AU by the conversion factor to get the distance in miles.
  4. Finally, verify your result using the calculator above.

Example Problem : 

Use the following variables as an example problem to test your knowledge.

Distance in astronomical units (AU) = 1.5

Conversion factor (CF) = 92,955,807.273026 miles

Distance in miles (M) = 1.5 * 92,955,807.273026 ≈ 139,433,710.909538 miles
