## Conversion formula

The conversion factor from kilometers to decimeters is 10000, which means that 1 kilometer is equal to 10000 decimeters:

1 km = 10000 dm

To convert 1 kilometers into decimeters we have to multiply 1 by the conversion factor in order to get the length amount from kilometers to decimeters. We can also form a simple proportion to calculate the result:

1 km → 10000 dm

1 km → L(dm)

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

L(dm) = 1 km × 10000 dm

L(dm) = 10000 dm

The final result is:

1 km → 10000 dm

We conclude that 1 kilometers is equivalent to 10000 decimeters:

1 kilometers = 10000 decimeters

## Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case 1 decimeter is equal to 0.0001 × 1 kilometers.

Another way is saying that 1 kilometers is equal to 1 ÷ 0.0001 decimeters.

## Approximate result

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

1 km ≅ 10000 dm

An alternative is also that one decimeter is approximately zero times one kilometers.
