## 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 90 kilometers into decimeters we have to multiply 90 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

90 km → L(dm)

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

L(dm) = 90 km × 10000 dm

L(dm) = 900000 dm

The final result is:

90 km → 900000 dm

We conclude that 90 kilometers is equivalent to 900000 decimeters:

90 kilometers = 900000 decimeters ## Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case 1 decimeter is equal to 1.1111111111111E-6 × 90 kilometers.

Another way is saying that 90 kilometers is equal to 1 ÷ 1.1111111111111E-6 decimeters.

## Approximate result

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

90 km ≅ 900000 dm

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