To convert US survey feet to astronomical units, multiply the value by 2.03747 × 10⁻¹². To go the other way, multiply astronomical units by 490,805,680,789 to get US survey feet.
| US Survey Feet (ftUS) | Astronomical Units (AU) |
|---|---|
| 1 ftUS | 2.03747 × 10⁻¹² AU |
| 5 ftUS | 1.01873 × 10⁻¹¹ AU |
| 10 ftUS | 2.03747 × 10⁻¹¹ AU |
| 25 ftUS | 5.09367 × 10⁻¹¹ AU |
| 50 ftUS | 1.01873 × 10⁻¹⁰ AU |
| 100 ftUS | 2.03747 × 10⁻¹⁰ AU |
| 250 ftUS | 5.09367 × 10⁻¹⁰ AU |
| 500 ftUS | 1.01873 × 10⁻⁹ AU |
| 1,000 ftUS | 2.03747 × 10⁻⁹ AU |
| 2,500 ftUS | 5.09367 × 10⁻⁹ AU |
| 5,000 ftUS | 1.01873 × 10⁻⁸ AU |
| 10,000 ftUS | 2.03747 × 10⁻⁸ AU |
| 100,000 ftUS | 2.03747 × 10⁻⁷ AU |
| 1,000,000 ftUS | 2.03747 × 10⁻⁶ AU |
25 ftUS × 2.03747 × 10⁻¹² = 5.09367 × 10⁻¹¹ AU
Try this example →250 ftUS × 2.03747 × 10⁻¹² = 5.09367 × 10⁻¹⁰ AU
Try this example →US survey foot (ftUS). The US survey foot is about 0.3048006 m, very slightly longer than the international foot, and was used in US land surveys.
Astronomical unit (AU). An astronomical unit is the average distance from the Earth to the Sun, about 149.6 million kilometers.
There are 2.03747 × 10⁻¹² astronomical units in one US survey foot.
Multiply the number of US survey feet by 2.03747 × 10⁻¹². For example, 10 US survey feet equal 2.03747 × 10⁻¹¹ astronomical units.
One astronomical unit equals 490,805,680,789 US survey feet.
2.03747 × 10⁻⁹ astronomical units. Other common values: 100 US survey feet = 2.03747 × 10⁻¹⁰ astronomical units and 10,000 US survey feet = 2.03747 × 10⁻⁸ astronomical units.
