Cosmic Distance Calculator
Convert a cosmic distance between AU, kilometres, light-years and parsecs.
Result
Calculated value—
Uses standard astronomy constants; results are mathematical estimates and should not replace mission-grade ephemerides or navigation data.
How it works
Convert a cosmic distance between AU, kilometres, light-years and parsecs.
Convert to kilometres, then divide by the target unit constant
How to use this calculator
What to enter
Enter or select the following as requested: Distance (AU); Input unit. Follow the units, valid ranges, examples, and options displayed beside each field.
What the result means
The astronomy result converts or estimates a distance, time, brightness, gravity, or orbital quantity from the entered astronomical values and model. Check the units, reference frame, object assumptions, and whether the formula uses idealized orbital or observational conditions.
When to use it
Use this for astronomy learning or preliminary calculations. Confirm the units and scientific model and consult reliable observational data when precision matters.
