How many AU in 400 km? The answer is 2.67384E-6 AU, so 400 km is equal to 2.67384E-6 AU. Let’s discuss it in detail!
First of all, we must know that km and AU are units of length, km is the abbreviation of Kilometer, AU is the abbreviation of Astronomical Unit.
Then, we want to convert 400 km into AU, we should get the conversion formula of km to AU first.
Fortunately, through the Kilometer to Astronomical Unit converter page, we can easily get the km to AU conversion formula: 1 km = 6.6846e-9 AU. The number 6.6846e-9 is called the conversion factor of km to AU.
So, convert km to AU, just multiply km by the conversion factor 6.6846e-9.
1 km = 6.6846e-9 AU
400 km = 400 * 6.6846e-9 AU = 2.67384E-6 AU
The result is out: 400 km = 2.67384E-6 AU.
Is not it simple?
If you still don’t understand, take it easy, we can give another example:
1 km = 6.6846e-9 AU
818 km = 818 * 6.6846e-9 AU = 5.4680028E-6 AU
Thus, 818 km = 5.4680028E-6 AU.
Well, through the above detailed explanation, you should have mastered the technique of how to convert km to AU.
