Conversion formula

The conversion factor from decimeters to meters is 0.1, which means that 1 decimeter is equal to 0.1 meters:

1 dm = 0.1 m

To convert 420 decimeters into meters we have to multiply 420 by the conversion factor in order to get the length amount from decimeters to meters. We can also form a simple proportion to calculate the result:

1 dm → 0.1 m

420 dm → L_(m)

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

L_(m) = 420 dm × 0.1 m

L_(m) = 42 m

The final result is:

420 dm → 42 m

We conclude that 420 decimeters is equivalent to 42 meters:

420 decimeters = 42 meters

Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case 1 meter is equal to 0.023809523809524 × 420 decimeters.

Another way is saying that 420 decimeters is equal to 1 ÷ 0.023809523809524 meters.

Approximate result

For practical purposes we can round our final result to an approximate numerical value. We can say that four hundred twenty decimeters is approximately forty-two meters:

420 dm ≅ 42 m

An alternative is also that one meter is approximately zero point zero two four times four hundred twenty decimeters.
