### Formulation

This tool uses a simple division method to change given millimeters into kilometers. It divides given millimeters by 1000000 because 1 millimeter is 1/1000000th part of a kilometer.

### Millimeter

SI unit of length or distance is 'meter'. Meter has different small and large prefixes. Millimeter is a smaller prefix used for length measurement in the SI system of units. It is equal to 1/1000th part of a meter.

### Kilometer

A kilometer is the larger prefix of meter. 1 kilometer is equal to 1000 meter.

## How to convert millimeters to kilometers

1 kilometer is equal to 1000000 millimeters:

1km = 1000000mm

The distance d in kilometers (km) is equal to the distance d in millimeters (mm) divided by 1000000:

d(km) = d(mm) / 1000000

#### Example

Convert 20 millimeters to kilometers:

d(km) = 20mm / 1000000 = 0.00002km

### How many millimeters in a kilometer

One kilometer is equal to 1000000 millimeter:

1km = 1km×1000000 = 1000000mm

### How many kilometers in a millimeter

One millimeter is equal to 0.000001 kilometers:

1mm = 1mm/1000000 = 0.000001km

### How to convert 8 millimeters to kilometers

Divide 8 millimeters by 1000000 to get kilometers:

8mm = 8mm/1000000 = 0.000008km
