Convert astronomical distance between astronomical units, light-years, parsecs, kilometres, and light-seconds.
How to use this calculator
For astronomical distance unit converter, enter Value, From unit, To unit using the unit or format beside each field. Select Calculate to apply the formula below, review all returned values together, and use Reset to restore the demonstrated inputs before testing another scenario.
Formula & calculation method
convertedValue = linearConvert(value,fromUnit,toUnit)Worked example
For a reproducible astronomical distance unit converter example, use Value: 1; From unit: Astronomical units; To unit: Light-years. The first returned value, converted value in the selected target unit, is calculated with linearConvert(value,fromUnit,toUnit); the other results describe the same scenario. Change one input at a time and keep its unit consistent when comparing scenarios.
Limitations to keep in mind
Conversions use the stated definitions and reference conditions. Confirm the unit convention, precision, temperature, pressure, and regional meaning before technical use.
