Conversion formula

The conversion factor from feet to decimeters is 3.048, which means that 1 foot is equal to 3.048 decimeters:

1 ft = 3.048 dm

To convert 685 feet into decimeters we have to multiply 685 by the conversion factor in order to get the length amount from feet to decimeters. We can also form a simple proportion to calculate the result:

1 ft → 3.048 dm

685 ft → L_(dm)

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

L_(dm) = 685 ft × 3.048 dm

L_(dm) = 2087.88 dm

The final result is:

685 ft → 2087.88 dm

We conclude that 685 feet is equivalent to 2087.88 decimeters:
