## 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 645 feet into decimeters we have to multiply 645 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

645 ft → L(dm)

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

L(dm) = 645 ft × 3.048 dm

L(dm) = 1965.96 dm

The final result is:

645 ft → 1965.96 dm

We conclude that 645 feet is equivalent to 1965.96 decimeters:
