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 103 kilometers into millimeters we have to multiply 103 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

103 km → L(mm)

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

L(mm) = 103 km × 1000000 mm

L(mm) = 103000000 mm

The final result is:

103 km → 103000000 mm

We conclude that 103 kilometers is equivalent to 103000000 millimeters:

103 kilometers = 103000000 millimeters
