Conversion formula

The conversion factor from decimeters to feet is 0.32808398950131, which means that 1 decimeter is equal to 0.32808398950131 feet:

1 dm = 0.32808398950131 ft

To convert 21.4 decimeters into feet we have to multiply 21.4 by the conversion factor in order to get the length amount from decimeters to feet. We can also form a simple proportion to calculate the result:

1 dm → 0.32808398950131 ft

21.4 dm → L_(ft)

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

L_(ft) = 21.4 dm × 0.32808398950131 ft

L_(ft) = 7.0209973753281 ft

The final result is:

21.4 dm → 7.0209973753281 ft

We conclude that 21.4 decimeters is equivalent to 7.0209973753281 feet:
