The **Astronomical Distance Conversion** calculator converts a measurement of distance into a list of equivalent distances in commonly used astronomical units.

**INSTRUCTIONS:** Choose units and enter the following:

- (
**D**) Input Distance

**Astronomical Distance (AD)**: The calculator returns the equivalent distance in the following units:

- (km) kilometers
- (mi) miles
- light-minutes
- (au) astronomical units
- (ly) light-years
- (pc) parsecs

However, these can be automatically converted to even more compatible units via the pull-down menu .

Astronomical distance units are often used in astronomy calculations when more conventional units such as kilometers are too small for easy comprehension, and the conversion from common length units to astronomical units is a simple linear transform.

- kilometers
- miles
- light-seconds
- light-minutes
- astronomical units (ua)
- light-hours
- light-days
- light-years
- kilolight-years
- parsecs
