To convert from inches to kilometers, we need a conversion factor to relate the two units involved in the problem. We
either multiply or divide this certain value to the original measurement
depending on what is asked. For this case, we use 1 meter is equal to 39.37 inches and 1000 meter is equal to 1 kilometer. We do as follows:
3.44 x 108 inches ( 1 meter / 39.37 inches ) ( 1 kilometer / 1000 meter ) = 8737.62 kilometers
