## 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

## Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case 1 decimeter is equal to 0.078115235595551 × 4.2 feet.

Another way is saying that 4.2 feet is equal to 1 ÷ 0.078115235595551 decimeters.

## Approximate result

For practical purposes we can round our final result to an approximate numerical value. We can say that four point two feet is approximately twelve point eight zero two decimeters:

4.2 ft ≅ 12.802 dm

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