## 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 7 feet into decimeters we have to multiply 7 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

7 ft → L(dm)

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

L(dm) = 7 ft × 3.048 dm

L(dm) = 21.336 dm

The final result is:

7 ft → 21.336 dm

We conclude that 7 feet is equivalent to 21.336 decimeters:

7 feet = 21.336 decimeters

## Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case 1 decimeter is equal to 0.04686914135733 × 7 feet.

Another way is saying that 7 feet is equal to 1 ÷ 0.04686914135733 decimeters.

## Approximate result

For practical purposes we can round our final result to an approximate numerical value. We can say that seven feet is approximately twenty-one point three three six decimeters:

7 ft ≅ 21.336 dm

An alternative is also that one decimeter is approximately zero point zero four seven times seven feet.
