The formulas for conversion are represented below:

ly = cm / 9,461x10^{17}

Example: 30 Centimeters in Light Years:

ly = cm / 9,461x10^{17}

ly = 30 / 9,461x10^{17}

ly = 3,171x10^{-17}

cm = ly * 9,461x10^{17}

Example: 1.5 Light Years in Centimeters:

cm = ly * 9,461x10^{17}

cm = 1,5 * 9,461x10^{17}

cm = 1,419x10^{18}

Considering that 1 Centimeter is equivalent to 1.057x10^{-18} Light Years, you can use a rule of three to obtain that **100 Centimeters equal 1.057x10 ^{-16< /sup>Light Years}**.

1 cm - 1,057x10^{-18} ly

100 cm - x

Apply the rule of three and get:

x ~~cm~~ = 100 x 1,057x10^{-18} ly~~cm~~

x = 1,057x10^{-16} ly

If every 1 Light Years we have 9.461x10^{17} Centimeters, just multiply the amount of Light Years (100) by 9.461x10^{17}, so you will get that **100 ly equals 100,000 cm**. Observe the calculation below:

cm = ly * 9,461x10^{17}

cm = 100 * 9,461x10^{17}

cm = 9,461x10^{19}
