Conversion formula

The conversion factor from centimeters to kilometers is 1.0E-5, which means that 1 centimeter is equal to 1.0E-5 kilometers:

1 cm = 1.0E-5 km

To convert 820 centimeters into kilometers we have to multiply 820 by the conversion factor in order to get the length amount from centimeters to kilometers. We can also form a simple proportion to calculate the result:

1 cm → 1.0E-5 km

820 cm → L_(km)

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

L_(km) = 820 cm × 1.0E-5 km

L_(km) = 0.0082 km

The final result is:

820 cm → 0.0082 km

We conclude that 820 centimeters is equivalent to 0.0082 kilometers:

820 centimeters = 0.0082 kilometers
