Conversion formula

The conversion factor from decimeters to kilometers is 0.0001, which means that 1 decimeter is equal to 0.0001 kilometers:

1 dm = 0.0001 km

To convert 3421 decimeters into kilometers we have to multiply 3421 by the conversion factor in order to get the length amount from decimeters to kilometers. We can also form a simple proportion to calculate the result:

1 dm → 0.0001 km

3421 dm → L_(km)

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

L_(km) = 3421 dm × 0.0001 km

L_(km) = 0.3421 km

The final result is:

3421 dm → 0.3421 km

We conclude that 3421 decimeters is equivalent to 0.3421 kilometers:

3421 decimeters = 0.3421 kilometers

Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case 1 kilometer is equal to 2.923121894183 × 3421 decimeters.

Another way is saying that 3421 decimeters is equal to 1 ÷ 2.923121894183 kilometers.

Approximate result

For practical purposes we can round our final result to an approximate numerical value. We can say that three thousand four hundred twenty-one decimeters is approximately zero point three four two kilometers:

3421 dm ≅ 0.342 km

An alternative is also that one kilometer is approximately two point nine two three times three thousand four hundred twenty-one decimeters.
