This converter allows you to convert ångströms [Å] to astronomical units [au] or astronomical units [au] to ångströms [Å]. 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 ångström [Å] ≈ 6.685 * 10-22 astronomical units [au]1 astronomical unit [au] ≈ 1.496 * 1021 ångströms [Å]

Convert ångströms to astronomical units

There are two simple ways to convert ångströms [Å] to astronomical units [au]. In the first calculation method, the value in ångströms [Å] is divided by the rounded conversion factor of 1.496 * 1021. The second method multiplies the value in ångströms [Å] by the rounded conversion factor of 6.685 * 10-22.

  • Astronomical units [au] ≈ ångströms [Å] ÷ (1.496 * 1021)
  • Astronomical units [au] ≈ ångströms [Å] * 6.685 * 10-22

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

Astronomical units [au] = ångströms [Å] ÷ 23,367 ÷ 64,021 ÷ 1012

Convert astronomical units to ångströms

Converting astronomical units [au] to ångströms [Å] 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 * 1021. The second variant is a division. Here, the value in astronomical units [au] is divided by the rounded conversion factor of 6.685 * 10-22.

  • Ångströms [Å] ≈ astronomical units [au] * 1.496 * 1021
  • Ångströms [Å] ≈ astronomical units [au] ÷ (6.685 * 10-22)

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 ångströms [Å] can be achieved using the following calculation method.

Ångströms [Å] = astronomical units [au] * 23,367 * 64,021 * 1012

Pressure

Hectopascals, millibars, and bars are just a few examples of the many units of pressure. The pressure converter makes conversion a breeze and ensures that the results are accurate and precise.

Pressure converter

Resistance

Electrical resistance is often expressed in ohms or kiloohms. However, it is also possible to use statohms or deciohms. The resistance converter is ideal for converting between different units of resistance.

Speed

While mph is used in the USA, km/h is the standard in Europe, and seafaring and aviation rely on knots. This speed converter is the perfect tool for accurately converting between various units of speed.
