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 100.9 feet into decimeters we have to multiply 100.9 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

100.9 ft → L_(dm)

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

L_(dm) = 100.9 ft × 3.048 dm

L_(dm) = 307.5432 dm

The final result is:

100.9 ft → 307.5432 dm

We conclude that 100.9 feet is equivalent to 307.5432 decimeters:

100.9 feet = 307.5432 decimeters
