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 1020 decimeters into kilometers we have to multiply 1020 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

1020 dm → L_(km)

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

L_(km) = 1020 dm × 0.0001 km

L_(km) = 0.102 km

The final result is:

1020 dm → 0.102 km

We conclude that 1020 decimeters is equivalent to 0.102 kilometers:

1020 decimeters = 0.102 kilometers

Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case 1 kilometer is equal to 9.8039215686275 × 1020 decimeters.

Another way is saying that 1020 decimeters is equal to 1 ÷ 9.8039215686275 kilometers.

Approximate result

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

1020 dm ≅ 0.102 km

An alternative is also that one kilometer is approximately nine point eight zero four times one thousand twenty decimeters.
