How to perform key conversions involving length measurements
The formulas for conversion are represented below:
Kilometers to Astronomical Units Formula
ua = km x 6,684589x10-9
Example: 10 kilometers in Astronomical Units:
ua = km x 6,684589x10-9
ua = 10 x 6,684589x10-9
ua = 6,684589x10-8
Astronomical Units to Kilometers Formula
km = ua / 6,684589x10-9
Example: 10 Astronomical Units in kilometers:
km = ua / 6,684589x10-9
km = 10 / 6,684589x10-9
km = 1.495.978.286,78
Frequently asked questions involving length and distance
1.5 km to Astronomical Unit
Considering that 1 kilometer is equivalent to 1000 Astronomical Units, you can use a rule of three to obtain that 1.5 km equals 1500 Astronomical Units.
1 km - 6,684589x10-9ua
1,5 km - x
Apply the rule of three and get:
x km = 1,5 x 6,684589x10-8 km ua
x = 1,002688350x10-8 ua
100 Astronomical Units is equal to how many kilometers?
If every 6.684589x10-9 AU we have 1 kilometer, just divide the amount of Astronomical Units (100) by 6.684589x10-9, so you will get that 100 AU equals 14,959,782,867.81 km. Observe the calculation below:
km = ua / 6,684589x10-9
Km = 100 / 6,684589x10-9
km = 14.959.782.867,81
