The conversion factor from meters to millimeters is 1000, which means that 1 meter is equal to 1000 millimeters:

1 m = 1000 mm

To convert 1638 meters into millimeters we have to multiply 1638 by the conversion factor in order to get the length amount from meters to millimeters. We can also form a simple proportion to calculate the result:

1 m → 1000 mm

1638 m → L_(mm)

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

L_(mm) = 1638 m × 1000 mm

L_(mm) = 1638000 mm

The final result is:

1638 m → 1638000 mm

We conclude that 1638 meters is equivalent to 1638000 millimeters:
