Answer:
5 mililmiters = 0,005 meters = 0,000005 kilometers
2 kilometers = 2000 meters
Explanation:
km / hectometer / decameter / meter / dcm / centimeter / milimeter
1000 m / 100 m / 10 m < 1 > 0,1 m/ 0,01 m / 0,0001 m
1 meter = 0, 1 decimeters / 0, 01 centimeters /0, 000 1 millimeters
1 meter = 10 decameters / 100 hectometers / 1000 kilometers
so 5 millimeters = 0,005 meters = 0, 000 005 kilometers
so 2 km = 2 000 meters = 2 000 000 millimeters
the reference unit of measure is the meter.
