To convert kilometers to astronomical units, multiply the value by 6.68459 × 10⁻⁹. To go the other way, multiply astronomical units by 149,598,000 to get kilometers.
| Kilometers (km) | Astronomical Units (AU) |
|---|---|
| 1 km | 6.68459 × 10⁻⁹ AU |
| 5 km | 3.34229 × 10⁻⁸ AU |
| 10 km | 6.68459 × 10⁻⁸ AU |
| 25 km | 1.67115 × 10⁻⁷ AU |
| 50 km | 3.34229 × 10⁻⁷ AU |
| 100 km | 6.68459 × 10⁻⁷ AU |
| 250 km | 1.67115 × 10⁻⁶ AU |
| 500 km | 3.34229 × 10⁻⁶ AU |
| 1,000 km | 6.68459 × 10⁻⁶ AU |
| 2,500 km | 1.67115 × 10⁻⁵ AU |
| 5,000 km | 3.34229 × 10⁻⁵ AU |
| 10,000 km | 6.68459 × 10⁻⁵ AU |
| 100,000 km | 0.000668459 AU |
| 1,000,000 km | 0.00668459 AU |
25 km × 6.68459 × 10⁻⁹ = 1.67115 × 10⁻⁷ AU
Try this example →250 km × 6.68459 × 10⁻⁹ = 1.67115 × 10⁻⁶ AU
Try this example →Kilometer (km). A kilometer is 1,000 meters and the standard unit for road distances in most countries, including India.
Astronomical unit (AU). An astronomical unit is the average distance from the Earth to the Sun, about 149.6 million kilometers.
There are 6.68459 × 10⁻⁹ astronomical units in one kilometer.
Multiply the number of kilometers by 6.68459 × 10⁻⁹. For example, 10 kilometers equal 6.68459 × 10⁻⁸ astronomical units.
One astronomical unit equals 149,598,000 kilometers.
6.68459 × 10⁻⁶ astronomical units. Other common values: 100 kilometers = 6.68459 × 10⁻⁷ astronomical units and 10,000 kilometers = 6.68459 × 10⁻⁵ astronomical units.
