This converter allows you to convert astronomical units [au] to kiloparsecs [kpc] or kiloparsecs [kpc] to astronomical units [au]. 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 astronomical unit [au] ≈ 4.848 * 10-9 kiloparsecs [kpc]1 kiloparsec [kpc] ≈ 2.063 * 108 astronomical units [au]

Convert astronomical units to kiloparsecs

There are two simple ways to convert astronomical units [au] to kiloparsecs [kpc]. In the first calculation method, the value in astronomical units [au] is divided by the rounded conversion factor of 2.063 * 108. The second method multiplies the value in astronomical units [au] by the rounded conversion factor of 4.848 * 10-9.

  • Kiloparsecs [kpc] ≈ astronomical units [au] ÷ (2.063 * 108)
  • Kiloparsecs [kpc] ≈ astronomical units [au] * 4.848 * 10-9

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

  • Kiloparsecs [kpc] = astronomical units [au] ÷ 30,857 * 23,367 * 64,021 ÷ 1013

Convert kiloparsecs to astronomical units

Converting kiloparsecs [kpc] to astronomical units [au] 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 2.063 * 108. The second variant is a division. Here, the value in kiloparsecs [kpc] is divided by the rounded conversion factor of 4.848 * 10-9.

  • Astronomical units [au] ≈ kiloparsecs [kpc] * 2.063 * 108
  • Astronomical units [au] ≈ kiloparsecs [kpc] ÷ (4.848 * 10-9)

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 astronomical units [au] can be achieved using the following calculation method.

  • Astronomical units [au] = kiloparsecs [kpc] * 30,857 ÷ 23,367 ÷ 64,021 * 1013
