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 1421 decimeters into kilometers we have to multiply 1421 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

1421 dm → L_(km)

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

L_(km) = 1421 dm × 0.0001 km

L_(km) = 0.1421 km

The final result is:

1421 dm → 0.1421 km

We conclude that 1421 decimeters is equivalent to 0.1421 kilometers:

1421 decimeters = 0.1421 kilometers

Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case 1 kilometer is equal to 7.0372976776918 × 1421 decimeters.

Another way is saying that 1421 decimeters is equal to 1 ÷ 7.0372976776918 kilometers.

Approximate result

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

1421 dm ≅ 0.142 km

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