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 9997 kilometers into millimeters we have to multiply 9997 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
9997 km → L(mm)
Solve the above proportion to obtain the length L in millimeters:
L(mm) = 9997 km × 1000000 mm
L(mm) = 9997000000 mm
The final result is:
9997 km → 9997000000 mm
We conclude that 9997 kilometers is equivalent to 9997000000 millimeters:
