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 1230 decimeters into kilometers we have to multiply 1230 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

1230 dm → L_(km)

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

L_(km) = 1230 dm × 0.0001 km

L_(km) = 0.123 km

The final result is:

1230 dm → 0.123 km

We conclude that 1230 decimeters is equivalent to 0.123 kilometers:

1230 decimeters = 0.123 kilometers

Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case 1 kilometer is equal to 8.130081300813 × 1230 decimeters.

Another way is saying that 1230 decimeters is equal to 1 ÷ 8.130081300813 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 thirty decimeters is approximately zero point one two three kilometers:

1230 dm ≅ 0.123 km

An alternative is also that one kilometer is approximately eight point one three times one thousand two hundred thirty decimeters.
