How the conversion works
The relationship is ly = yd × 9.665215626 × 10^-17. Both units measure length, so the conversion is a fixed factor that never changes. The figure is exact rather than approximate: since the international yard and pound agreement of 1959, an inch is defined as exactly 25.4 millimetres and a pound as exactly 0.45359237 kilograms, and every other imperial and US customary unit here is derived from those two.
Common questions
- How many light-years are in one yard?
- One yard equals 9.665 × 10^-17 light-years. ly = yd × 9.665215626 × 10^-17.
- How do you convert yards to light-years?
- Use ly = yd × 9.665215626 × 10^-17. So 10 yd is 9.665 × 10^-16 ly.
- How many yards are in one light-year?
- One light-year equals 1.0346381 × 10^16 yards, which is the reverse of the conversion above.
