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 340 decimeters into kilometers we have to multiply 340 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

340 dm → L_(km)

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

L_(km) = 340 dm × 0.0001 km

L_(km) = 0.034 km

The final result is:

340 dm → 0.034 km

We conclude that 340 decimeters is equivalent to 0.034 kilometers:

340 decimeters = 0.034 kilometers

Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case 1 kilometer is equal to 29.411764705882 × 340 decimeters.

Another way is saying that 340 decimeters is equal to 1 ÷ 29.411764705882 kilometers.

Approximate result

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

340 dm ≅ 0.034 km

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