You can easily convert 1 millimeter into kilometers using each unit definition:

- Millimeter
- milli m = 0.001 m
- Kilometers
- kilo m = 1000 m

With this information, you can calculate the quantity of kilometers 1 millimeter is equal to.

## ¿How many km are there in 1 mm?

In 1 mm there are 1e-06 km.

Which is the same to say that **1 millimeter is 1e-06 kilometers**.

One millimeter equals to one kilometers. *Approximation

### ¿What is the inverse calculation between 1 kilometer and 1 millimeter?

Performing the inverse calculation of the relationship between units, we obtain that **1 kilometer is 1000000 times 1 millimeter**.

A kilometer is one million times one millimeter. *Approximation
