1 thou [mil] ≈ 1.698 * 10-16 astronomical units [au]1 astronomical unit [au] ≈ 5.89 * 1015 thous [mil]

Convert thous to astronomical units

There are two simple ways to convert thous [mil] to astronomical units [au]. In the first calculation method, the value in thous [mil] is divided by the rounded conversion factor of 5.89 * 1015. The second method multiplies the value in thous [mil] by the rounded conversion factor of 1.698 * 10-16.

  • Astronomical units [au] ≈ thous [mil] ÷ (5.89 * 1015)
  • Astronomical units [au] ≈ thous [mil] * 1.698 * 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 thous [mil] to astronomical units [au] can be achieved using the following calculation method.

  • Astronomical units [au] = thous [mil] ÷ 23,367 ÷ 64,021 * 254 ÷ 109

Convert astronomical units to thous

Converting astronomical units [au] to thous [mil] 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 5.89 * 1015. The second variant is a division. Here, the value in astronomical units [au] is divided by the rounded conversion factor of 1.698 * 10-16.

  • Thous [mil] ≈ astronomical units [au] * 5.89 * 1015
  • Thous [mil] ≈ astronomical units [au] ÷ (1.698 * 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 astronomical units [au] to thous [mil] can be achieved using the following calculation method.

  • Thous [mil] = astronomical units [au] * 23,367 * 64,021 ÷ 254 * 109
