## 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 18 feet into decimeters we have to multiply 18 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

18 ft → L(dm)

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

L(dm) = 18 ft × 3.048 dm

L(dm) = 54.864 dm

The final result is:

18 ft → 54.864 dm

We conclude that 18 feet is equivalent to 54.864 decimeters:

18 feet = 54.864 decimeters

## Alternative conversion
