Kilometers
Meters
You would use kilometers.
millimeters are a measure of distance cubic centimeters are a measure of volume the only similarity is that both are metric
The metric system is used to measure distance in Brazil.
distance
Distance is measured metrically in meters
A global positioning system (GPS)
After meters in the metric system, the next largest unit of measurement is kilometers. One kilometer is equal to 1000 meters. Kilometers are commonly used to measure longer distances, such as the distance between cities or countries.
The word, metric, means referring to a measure: it is a measure of some characteristic and how it is measured depends on the way in which it is defined. This may be illustrated by considering the metric for distance. Conventionally, the metric for the distance between two points is the length of the straight line joining them. However, on the surface of a sphere, for example, it is a length along the "Great Circle". In a Minkovski space (for example a road grid like in Manhattan) it is the North-South distance plus the East-West distance.
Any unit could be used. The most common for distances withterrestrial orders of magnitude is the kilometer = 1,000 meters.
Metric threads are called that way, because you measure the distance between the threads (at the highest point), in millimeters., As opposed to SAE (standard), which are measured by the number of threads in an inch.
Use units of millimeters, meters, or kilometers.
