How many kilometers in a millimeter

There are 0.000001 (one millionth) of a kilometer in a millimeter.

The metric system uses prefixes to represent different orders of magnitude. In this case, the prefix “milli-” denotes a factor of 1/1000 or 0.001.

So, when you have 1 millimeter (1 mm), you can convert it to kilometers by multiplying by 0.001:

1 millimeter = 0.001 meters 1 meter = 0.001 kilometers

Therefore:

1 millimeter = 0.001 meters x 0.001 kilometers/meter = 0.000001 kilometers

So, there are 0.000001 kilometers in 1 millimeter.
