How do you convert grams to kilometers?

Answer 1

You do not. A gram is a measure of mass, whereas a kilometre is a measure of distance. The two measure different things and, according to the basic principles of dimensional analysis, conversion from one to the other is not valid.

Answer 2

This is an impossible question. A kilometer is a measure of distance and a gram is a measure of weight . This is like saying how do I convert an apple into an orange.
