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 815 kilometers into centimeters we have to multiply 815 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

815 km → L_(cm)

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

L_(cm) = 815 km × 100000 cm

L_(cm) = 81500000 cm

The final result is:

815 km → 81500000 cm

We conclude that 815 kilometers is equivalent to 81500000 centimeters:
