Answer:
nm, dm, km, m
Explanation:
1 nanometer = 1e-12 (0.000000000001) kilometers
1 decimeter = 1e-4 (0.0001) kilometers
1 kilometer = 1 kilometer
Regardless of whether 'm' stands for mile or meter, it's still larger than all of these being approx. 1.61 and 1e-3 (0.001) kilometers respectively.
in the future, please provide the exact units.
Such as:
nanometers, decimeters, kilometers, meters
