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 1997 decimeters into kilometers we have to multiply 1997 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

1997 dm → L_(km)

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

L_(km) = 1997 dm × 0.0001 km

L_(km) = 0.1997 km

The final result is:

1997 dm → 0.1997 km

We conclude that 1997 decimeters is equivalent to 0.1997 kilometers:

1997 decimeters = 0.1997 kilometers

Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case 1 kilometer is equal to 5.0075112669004 × 1997 decimeters.

Another way is saying that 1997 decimeters is equal to 1 ÷ 5.0075112669004 kilometers.

Approximate result

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

1997 dm ≅ 0.2 km

An alternative is also that one kilometer is approximately five point zero zero eight times one thousand nine hundred ninety-seven decimeters.
