10000 km to light year conversion result above is displayed in three different forms: as a decimal (which could be rounded), in scientific notation (scientific form, standard index form or standard form in the United Kingdom) and as a fraction (exact result). Every display form has its own advantages and in different situations particular form is more convenient than another. For example usage of scientific notation when working with big numbers is recommended due to easier reading and comprehension. Usage of fractions is recommended when more precision is needed.
If we want to calculate how many Light Years are 10000 Kilometers we have to multiply 10000 by 5 and divide the product by 47303652362904. So for 10000 we have: (10000 × 5) ÷ 47303652362904 = 50000 ÷ 47303652362904 = 1.0570008340246E-9 Light Years
So finally 10000 km = 0.0000000010570008340246 light year
