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 670 kilometers into millimeters we have to multiply 670 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

670 km → L_(mm)

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

L_(mm) = 670 km × 1000000 mm

L_(mm) = 670000000 mm

The final result is:

670 km → 670000000 mm

We conclude that 670 kilometers is equivalent to 670000000 millimeters:
