## Conversion formula

The conversion factor from kilometers to millimeters is 1000000, which means that 1 kilometer is equal to 1000000 millimeters:

1 km = 1000000 mm

To convert 268 kilometers into millimeters we have to multiply 268 by the conversion factor in order to get the length amount from kilometers to millimeters. We can also form a simple proportion to calculate the result:

1 km → 1000000 mm

268 km → L(mm)

Solve the above proportion to obtain the length L in millimeters:

L(mm) = 268 km × 1000000 mm

L(mm) = 268000000 mm

The final result is:

268 km → 268000000 mm

We conclude that 268 kilometers is equivalent to 268000000 millimeters:

268 kilometers = 268000000 millimeters
