Conversion formula

The conversion factor from kilometers to centimeters is 100000, which means that 1 kilometer is equal to 100000 centimeters:

1 km = 100000 cm

To convert 423 kilometers into centimeters we have to multiply 423 by the conversion factor in order to get the length amount from kilometers to centimeters. We can also form a simple proportion to calculate the result:

1 km → 100000 cm

423 km → L_(cm)

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

L_(cm) = 423 km × 100000 cm

L_(cm) = 42300000 cm

The final result is:

423 km → 42300000 cm

We conclude that 423 kilometers is equivalent to 42300000 centimeters:
