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
