  • Light years [ly] ≈ thous [mil] * 2.685 * 10-21

However, rounded conversion values are only suitable for rough conversions, as rounding errors can occur in the calculation result. The most accurate conversion of thous [mil] to light years [ly] can be achieved using the following calculation method.

  • Light years [ly] = thous [mil] ÷ 3,981,712 ÷ 23,760,459 * 254 ÷ 109

Convert light years to thous
