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 feet into decimeters we have to multiply 42 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 ft → L_(dm)

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

L_(dm) = 42 ft × 3.048 dm

L_(dm) = 128.016 dm

The final result is:

42 ft → 128.016 dm

We conclude that 42 feet is equivalent to 128.016 decimeters:

42 feet = 128.016 decimeters

Alternative conversion

Another way is saying that 42 feet is equal to 1 ÷ 0.0078115235595551 decimeters.

Approximate result

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

42 ft ≅ 128.016 dm

An alternative is also that one decimeter is approximately zero point zero zero eight times forty-two feet.
