Conversion of Decimeters to Kilometers

The video tutorial explains how to convert 51.8 decimeters to kilometers. It begins by converting decimeters to meters, explaining that 1 decimeter is 1/10 of a meter. The tutorial then converts meters to kilometers, noting that 1 kilometer equals 1,000 meters. The process involves unit cancellation and moving the decimal point to the left when dividing by powers of ten. The final result is 51.8 decimeters equaling 0.00518 kilometers, with a reality check to ensure the conversion makes sense.
