An ant would be measured in millimeters. An ant that is over a centimeter long would be an unusually large species (such as the Dinoponera of the Amazon which reaches 3 cm or 30 mm). At a meter long, it would be the size of a medium to large dog. At a kilometer it would cover several city blocks.
Meters.
0.008 millimeters is not equivalent. There are 1000 meters in a kilometer, 100 centimeters in a meter, and 10 millimeters in a centimeter. So the equivalent value in millimeters would be 800 mm.

0.008 millimeters is not equivalent. There are 1000 meters in a kilometer, 100 centimeters in a meter, and 10 millimeters in a centimeter. So the equivalent value in millimeters would be 800 mm.
centimeters
Any of those units could be used. 'Kilometers' would result in the most convenient number.
If you have three measurements of length (meters, centimeters, millimeters) and you multiply them together, you will end up with a measure of volume (liters). Of course, if you were to actually do this, you would want to convert all of the lengths into a common unit (convert centimeters and millimeters to meters or convert meters and centimeters to millimeters).
CM
There are 1000 meters in a kilometer, so that would mean the answer is: 64.4 kms. (simply divide your meters by 1000 to get this answer) The metric system makes it very easy to convert between centimeters, meters and kilometers. Further Info There are: 10 millimeters in a centimeter 100 centimeters in a meter 1000 meters in a kilometer. So 64.4kms is 64,400 meters (64.4 x 1000) 6,440,000 centimeters (64,440 x 100) 64,400,000 millimeters (6,440,000 x 10)
