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 791 kilometers into millimeters we have to multiply 791 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

791 km → L(mm)

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

L(mm) = 791 km × 1000000 mm

L(mm) = 791000000 mm

The final result is:

791 km → 791000000 mm

We conclude that 791 kilometers is equivalent to 791000000 millimeters:
