1 inch [in] ≈ 1.698 * 10-13 astronomical units [au]1 astronomical unit [au] ≈ 5.89 * 1012 inches [in]

Convert inches to astronomical units

There are two simple ways to convert inches [in] to astronomical units [au]. In the first calculation method, the value in inches [in] is divided by the rounded conversion factor of 5.89 * 1012. The second method multiplies the value in inches [in] by the rounded conversion factor of 1.698 * 10-13.

  • Astronomical units [au] ≈ inches [in] ÷ (5.89 * 1012)
  • Astronomical units [au] ≈ inches [in] * 1.698 * 10-13

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

  • Astronomical units [au] = inches [in] ÷ 23,367 ÷ 64,021 * 254 ÷ 106

Convert astronomical units to inches

Converting astronomical units [au] to inches [in] 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 * 1012. The second variant is a division. Here, the value in astronomical units [au] is divided by the rounded conversion factor of 1.698 * 10-13.

  • Inches [in] ≈ astronomical units [au] * 5.89 * 1012
  • Inches [in] ≈ astronomical units [au] ÷ (1.698 * 10-13)

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 inches [in] can be achieved using the following calculation method.

  • Inches [in] = astronomical units [au] * 23,367 * 64,021 ÷ 254 * 106
