This converter allows you to convert light years [ly] to kiloparsecs [kpc] or kiloparsecs [kpc] to light years [ly]. 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 light year [ly] ≈ 3.066 * 10-4 kiloparsecs [kpc]1 kiloparsec [kpc] ≈ 3,261.5875 light years [ly]

Convert light years to kiloparsecs

There are two simple ways to convert light years [ly] to kiloparsecs [kpc]. In the first calculation method, the value in light years [ly] is divided by the rounded conversion factor of 3,261.5875. The second method multiplies the value in light years [ly] by the rounded conversion factor of 3.066 * 10-4.

  • Kiloparsecs [kpc] ≈ light years [ly] ÷ 3,261.5875
  • Kiloparsecs [kpc] ≈ light years [ly] * 3.066 * 10-4

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

  • Kiloparsecs [kpc] = light years [ly] ÷ 30,857 * 3,981,712 * 23,760,459 ÷ 1013

Convert kiloparsecs to light years

Converting kiloparsecs [kpc] to light years [ly] is easy and can be done in two ways. The first method involves multiplication, in which the value in kiloparsecs [kpc] is multiplied by the rounded conversion factor of 3,261.5875. The second variant is a division. Here, the value in kiloparsecs [kpc] is divided by the rounded conversion factor of 3.066 * 10-4.

  • Light years [ly] ≈ kiloparsecs [kpc] * 3,261.5875
  • Light years [ly] ≈ kiloparsecs [kpc] ÷ (3.066 * 10-4)

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

  • Light years [ly] = kiloparsecs [kpc] * 30,857 ÷ 3,981,712 ÷ 23,760,459 * 1013
