How to perform key conversions involving length measurements
The formulas for conversion are represented below:
Kilometers to Light Year Formula
ly = km / 9,461x1012
Example: 1000 kilometers in Light Year:
ly = km / 9,461x1012
ly = 1000 / 9,461x1012
ly = 1,057x10-10
Light Year to Kilometers Formula
km = ly * 9,461x1012
Example: 3 Light Years in kilometers:
km = ly * 9,461x1012
km = 3 * 9,461x1012
km = 2,838x1013
Frequently asked questions involving length and distance
1 million kilometers in light years
Considering that 1 kilometer is equivalent to 1.057000834x10-13 light-years, you can use a rule of three to obtain that 1000000 km equals 1.057000834x10- 7 light years.
1 km - 1,057000834x10-13ly
1000000 km - x
Apply the rule of three and get:
x km = 1,057000834x10-7 kmly
x = 1,057000834x10-7 ly
100 light years equals how many kilometers?
If every 9,461x1012 kilometer we have 1 light year, just multiply the number of light years (100) by 9,461x1012, so you will get that 100 light years equals 9,461x1014 km. Observe the calculation below:
km = ly * 9,461x1012
Km = 100 * 9,461x1012
km = 9,461x1014
