This converter allows you to convert feet [ft] to astronomical units [au] or astronomical units [au] to feet [ft]. 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 foot [ft] ≈ 2.037 * 10-12 astronomical units [au]1 astronomical unit [au] ≈ 4.908 * 1011 feet [ft]

Convert feet to astronomical units

There are two simple ways to convert feet [ft] to astronomical units [au]. In the first calculation method, the value in feet [ft] is divided by the rounded conversion factor of 4.908 * 1011. The second method multiplies the value in feet [ft] by the rounded conversion factor of 2.037 * 10-12.

  • Astronomical units [au] ≈ feet [ft] ÷ (4.908 * 1011)
  • Astronomical units [au] ≈ feet [ft] * 2.037 * 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 feet [ft] to astronomical units [au] can be achieved using the following calculation method.

  • Astronomical units [au] = feet [ft] ÷ 23,367 ÷ 64,021 * 3,048 ÷ 106

Convert astronomical units to feet

Converting astronomical units [au] to feet [ft] 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 4.908 * 1011. The second variant is a division. Here, the value in astronomical units [au] is divided by the rounded conversion factor of 2.037 * 10-12.

  • Feet [ft] ≈ astronomical units [au] * 4.908 * 1011
  • Feet [ft] ≈ astronomical units [au] ÷ (2.037 * 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 astronomical units [au] to feet [ft] can be achieved using the following calculation method.

  • Feet [ft] = astronomical units [au] * 23,367 * 64,021 ÷ 3,048 * 106
