Astronomy Distance Converters
Convert astronomical and space-scale distances across AU, light-years, parsecs, lunar distance, and standard metric or imperial units.
Explanation
This hub groups astronomy distance conversions used for educational, observational, and astrophysical scale comparisons. Unit relationships are normalized through fixed meter-based constants, including the exact astronomical unit definition and standard light-time/parsec relationships used in scientific references.
How to use this hub
- Choose a converter family.
- If converting to/from grams from a volume unit, select an ingredient.
- For pure unit changes (volume↔volume or weight↔weight), use universal conversions.
If your conversion includes grams, you’ll choose an ingredient; otherwise you won’t.
Frequently Asked Questions
What units are included in this astronomy distance hub?
It includes AU, light-seconds, light-years, parsecs (pc, kpc, Mpc, Gpc), lunar distance, Earth/Solar radii and diameters, plus km, meters, and miles.
Are these conversion factors fixed constants?
Yes. Every factor is derived from fixed meter-based constants so mirror conversions remain consistent and reversible.
Can I use decimal inputs for very large distances?
Yes. Decimal values are supported for both near-Earth and deep-space scale conversions.
