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 42.4 feet into decimeters we have to multiply 42.4 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

42.4 ft → L_(dm)

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

L_(dm) = 42.4 ft × 3.048 dm

L_(dm) = 129.2352 dm

The final result is:

42.4 ft → 129.2352 dm

We conclude that 42.4 feet is equivalent to 129.2352 decimeters:

42.4 feet = 129.2352 decimeters

Alternative conversion
