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


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
