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 620.3 kilometers into millimeters we have to multiply 620.3 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
620.3 km → L(mm)
Solve the above proportion to obtain the length L in millimeters:
L(mm) = 620.3 km × 1000000 mm
L(mm) = 620300000 mm
The final result is:
620.3 km → 620300000 mm
