Formula and precision

Value in m = Value in ly × 9460730472580800

1 ly is equal to 9460730472580800 m.

Yes. Conversions run locally in your browser using verified ratios and display up to 8 decimals. Some categories like temperature and fuel use specialized formulas.

Use smaller units for higher precision, then convert back if needed.
Temperature and fuel categories can’t be reduced to one constant multiplier.
Symbols vary by region (US/UK gallons, metric vs. imperial abbreviations).
For engineering work, validate with a second reference and keep unit symbols.

Quick examples

Example: 1 ly = 9460730472580800 m.

Value (ly)	Result (m)

Common mistakes and definitions

Rounding too early (convert first, then round at the end).
Mixing similar-looking symbols (for example, “m” vs “mm”, or “b” vs “B”).
Copying values without the unit symbol, which makes validation harder.
