The formulas for conversion are represented below:
ly = cm / 9,461x1017
Example: 30 Centimeters in Light Years:
ly = cm / 9,461x1017
ly = 30 / 9,461x1017
ly = 3,171x10-17
cm = ly * 9,461x1017
Example: 1.5 Light Years in Centimeters:
cm = ly * 9,461x1017
cm = 1,5 * 9,461x1017
cm = 1,419x1018
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 lycm
x = 1,057x10-16 ly
If every 1 Light Years we have 9.461x1017 Centimeters, just multiply the amount of Light Years (100) by 9.461x1017, so you will get that 100 ly equals 100,000 cm. Observe the calculation below:
cm = ly * 9,461x1017
cm = 100 * 9,461x1017
cm = 9,461x1019
