This converter allows you to convert meters [m] to light years [ly] or light years [ly] to meters [m]. Calculations are performed in both directions. The calculation result and the entered value are displayed with up to 20 decimal places for maximum accuracy.

1 meter [m] ≈ 1.057 * 10-16 light years [ly]1 light year [ly] ≈ 9.461 * 1015 meters [m]

Convert meters to light years

There are two simple ways to convert meters [m] to light years [ly]. In the first calculation method, the value in meters [m] is divided by the rounded conversion factor of 9.461 * 1015. The second method multiplies the value in meters [m] by the rounded conversion factor of 1.057 * 10-16.

  • Light years [ly] ≈ meters [m] ÷ (9.461 * 1015)
  • Light years [ly] ≈ meters [m] * 1.057 * 10-16

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

  • Light years [ly] = meters [m] ÷ 3,981,712 ÷ 23,760.459 ÷ 105

Convert light years to meters

Converting light years [ly] to meters [m] is easy and can be done in two ways. The first method involves multiplication, in which the value in light years [ly] is multiplied by the rounded conversion factor of 9.461 * 1015. The second variant is a division. Here, the value in light years [ly] is divided by the rounded conversion factor of 1.057 * 10-16.

  • Meters [m] ≈ light years [ly] * 9.461 * 1015
  • Meters [m] ≈ light years [ly] ÷ (1.057 * 10-16)

However, rounded conversion values do not allow for exact calculations because rounding errors can occur in the calculation result. The most accurate conversion of light years [ly] to meters [m] can be achieved using the following calculation method.

  • Meters [m] = light years [ly] * 3,981,712 * 23,760.459 * 105
