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 45.4 feet into decimeters we have to multiply 45.4 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

45.4 ft → L_(dm)

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

L_(dm) = 45.4 ft × 3.048 dm

L_(dm) = 138.3792 dm

The final result is:

45.4 ft → 138.3792 dm

We conclude that 45.4 feet is equivalent to 138.3792 decimeters:

45.4 feet = 138.3792 decimeters
