This converter allows you to convert astronomical units [au] to megaparsecs [Mpc] or megaparsecs [Mpc] 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 * 10-12 megaparsecs [Mpc]1 megaparsec [Mpc] ≈ 2.063 * 1011 astronomical units [au]

Convert astronomical units to megaparsecs

There are two simple ways to convert astronomical units [au] to megaparsecs [Mpc]. In the first calculation method, the value in astronomical units [au] is divided by the rounded conversion factor of 2.063 * 1011. The second method multiplies the value in astronomical units [au] by the rounded conversion factor of 4.848 * 10-12.

  • Megaparsecs [Mpc] ≈ astronomical units [au] ÷ (2.063 * 1011)
  • Megaparsecs [Mpc] ≈ astronomical units [au] * 4.848 * 10-12

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 megaparsecs [Mpc] can be achieved using the following calculation method.

  • Megaparsecs [Mpc] = astronomical units [au] ÷ 30,857 * 23,367 * 64,021 ÷ 1016

Convert megaparsecs to astronomical units

Converting megaparsecs [Mpc] to astronomical units [au] is easy and can be done in two ways. The first method involves multiplication, in which the value in megaparsecs [Mpc] is multiplied by the rounded conversion factor of 2.063 * 1011. The second variant is a division. Here, the value in megaparsecs [Mpc] is divided by the rounded conversion factor of 4.848 * 10-12.

  • Astronomical units [au] ≈ megaparsecs [Mpc] * 2.063 * 1011
  • Astronomical units [au] ≈ megaparsecs [Mpc] ÷ (4.848 * 10-12)

However, rounded conversion values do not allow for exact calculations because rounding errors can occur in the calculation result. The most accurate conversion of megaparsecs [Mpc] to astronomical units [au] can be achieved using the following calculation method.

  • Astronomical units [au] = megaparsecs [Mpc] * 30,857 ÷ 23,367 ÷ 64,021 * 1016
