## 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 7.8 kilometers into decimeters we have to multiply 7.8 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

7.8 km → L_{(dm)}

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

L_{(dm)} = 7.8 km × 10000 dm

L_{(dm)} = 78000 dm

The final result is:

7.8 km → 78000 dm

We conclude that **7.8 kilometers is equivalent to 78000 decimeters**:

7.8 kilometers = 78000 decimeters

## Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case **1 decimeter is equal to 1.2820512820513E-5 × 7.8 kilometers**.

Another way is saying that *7.8 kilometers is equal to 1 ÷ 1.2820512820513E-5 decimeters*.

## Approximate result

For practical purposes we can round our final result to an approximate numerical value. We can say that **seven point eight kilometers is approximately seventy-eight thousand decimeters**:

7.8 km ≅ 78000 dm

An alternative is also that *one decimeter is approximately zero times seven point eight kilometers*.
