How to Use This Calculator
Select the source unit
Pick the unit your distance is currently in (e.g., kilometers, miles, nautical miles).
Select the destination unit
Choose the unit you need (metric, imperial, or astronomical).
Type the value
Enter the distance and let the converter show the result plus every other supported unit.
Formula
All conversions route through meters as the base SI unit.
Meters = Value Ă— (meters per source unit)
Converted Value = Meters Ă· (meters per destination unit)
Unit factors follow international definitions (e.g., 1 mile = 1,609.344 meters).
Use the formula breakdown to confirm the calculation logic or perform the conversion manually if needed.
Full Description
Distance units span multiple systems—metric, imperial, nautical, and astronomical. This converter centralizes them with precise factors, eliminating repeated lookups and manual calculations.
By routing through meters, it preserves accuracy across extreme scales: from nanometers and angstroms up to astronomical units and light-years.
The breakdown table helps you compare a distance across the full unit list, which is especially useful for education, engineering references, and content creation.
Frequently Asked Questions
Can I convert extremely large or small distances?
Yes. JavaScript’s double precision covers a wide range. For extremely large astronomy values, consider scientific notation.
How accurate are the unit factors?
They follow exact definitions from NIST and the IAU where applicable. Inches and miles use their legal metric equivalents.
Does it handle negative distances?
Negative values are allowed to represent direction or offsets, though physical distances are typically non-negative.
What about custom units?
Extend the `length.ts` conversion map with additional units by defining meters-per-unit factors.
