This converter allows you to convert attometers [am] to astronomical units [au] or astronomical units [au] to attometers [am]. 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 attometer [am] ≈ 6.685 * 10-30 astronomical units [au]1 astronomical unit [au] ≈ 1.496 * 1029 attometers [am]

Convert attometers to astronomical units

There are two simple ways to convert attometers [am] to astronomical units [au]. In the first calculation method, the value in attometers [am] is divided by the rounded conversion factor of 1.496 * 1029. The second method multiplies the value in attometers [am] by the rounded conversion factor of 6.685 * 10-30.

  • Astronomical units [au] ≈ attometers [am] ÷ (1.496 * 1029)
  • Astronomical units [au] ≈ attometers [am] * 6.685 * 10-30

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

  • Astronomical units [au] = attometers [am] ÷ 23,367 ÷ 64,021 ÷ 1020

Convert astronomical units to attometers

Converting astronomical units [au] to attometers [am] is easy and can be done in two ways. The first method involves multiplication, in which the value in astronomical units [au] is multiplied by the rounded conversion factor of 1.496 * 1029. The second variant is a division. Here, the value in astronomical units [au] is divided by the rounded conversion factor of 6.685 * 10-30.

  • Attometers [am] ≈ astronomical units [au] * 1.496 * 1029
  • Attometers [am] ≈ astronomical units [au] ÷ (6.685 * 10-30)

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

  • Attometers [am] = astronomical units [au] * 23,367 * 64,021 * 1020
