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 300 decimeters into kilometers we have to multiply 300 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

300 dm → L_(km)

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

L_(km) = 300 dm × 0.0001 km

L_(km) = 0.03 km

The final result is:

300 dm → 0.03 km

We conclude that 300 decimeters is equivalent to 0.03 kilometers:

300 decimeters = 0.03 kilometers

Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case 1 kilometer is equal to 33.333333333333 × 300 decimeters.

Another way is saying that 300 decimeters is equal to 1 ÷ 33.333333333333 kilometers.

Approximate result

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

300 dm ≅ 0.03 km

An alternative is also that one kilometer is approximately thirty-three point three three three times three hundred decimeters.
