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 1242 decimeters into kilometers we have to multiply 1242 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

1242 dm → L_(km)

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

L_(km) = 1242 dm × 0.0001 km

L_(km) = 0.1242 km

The final result is:

1242 dm → 0.1242 km

We conclude that 1242 decimeters is equivalent to 0.1242 kilometers:

1242 decimeters = 0.1242 kilometers

Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case 1 kilometer is equal to 8.0515297906602 × 1242 decimeters.

Another way is saying that 1242 decimeters is equal to 1 ÷ 8.0515297906602 kilometers.

Approximate result

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

1242 dm ≅ 0.124 km

An alternative is also that one kilometer is approximately eight point zero five two times one thousand two hundred forty-two decimeters.
