The metric table goes: millimeters, centimeters, decimeters, meters, dekameters, hectometers, kilometers. To move up the table, move the decimal point one to the left. To go from millimeters to centimeters, your answer would be 8,340,000.0, which is 8,340,000. However, you want kilometers. This would be 83.4 kilometers. Hope this helps!
