## 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 3 kilometers into decimeters we have to multiply 3 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

3 km → L(dm)

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

L(dm) = 3 km × 10000 dm

L(dm) = 30000 dm

The final result is:

3 km → 30000 dm

We conclude that 3 kilometers is equivalent to 30000 decimeters:

3 kilometers = 30000 decimeters

## Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case 1 decimeter is equal to 3.3333333333333E-5 × 3 kilometers.

Another way is saying that 3 kilometers is equal to 1 ÷ 3.3333333333333E-5 decimeters.

## Approximate result

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

3 km ≅ 30000 dm

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