Conversion formula

The conversion factor from centimeters to decimeters is 0.1, which means that 1 centimeter is equal to 0.1 decimeters:

1 cm = 0.1 dm

To convert 6690 centimeters into decimeters we have to multiply 6690 by the conversion factor in order to get the length amount from centimeters to decimeters. We can also form a simple proportion to calculate the result:

1 cm → 0.1 dm

6690 cm → L_(dm)

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

L_(dm) = 6690 cm × 0.1 dm

L_(dm) = 669 dm

The final result is:

6690 cm → 669 dm

We conclude that 6690 centimeters is equivalent to 669 decimeters:
