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 4.2 feet into decimeters we have to multiply 4.2 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

4.2 ft → L(dm)

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

L(dm) = 4.2 ft × 3.048 dm

L(dm) = 12.8016 dm

The final result is:

4.2 ft → 12.8016 dm

We conclude that 4.2 feet is equivalent to 12.8016 decimeters:

4.2 feet = 12.8016 decimeters

4.2 feet is equal to 12.802 decimeters
