## Conversion formula

The conversion factor from centimeters to decimeters is 0.1, which means that 1 centimeter is equal to 0.1 decimeters:

1 cm = 0.1 dm

To convert 450 centimeters into decimeters we have to multiply 450 by the conversion factor in order to get the length amount from centimeters to decimeters. We can also form a simple proportion to calculate the result:

1 cm → 0.1 dm

450 cm → L(dm)

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

L(dm) = 450 cm × 0.1 dm

L(dm) = 45 dm

The final result is:

450 cm → 45 dm

We conclude that 450 centimeters is equivalent to 45 decimeters:

450 centimeters = 45 decimeters

## Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case 1 decimeter is equal to 0.022222222222222 × 450 centimeters.

Another way is saying that 450 centimeters is equal to 1 ÷ 0.022222222222222 decimeters.

## Approximate result

For practical purposes we can round our final result to an approximate numerical value. We can say that four hundred fifty centimeters is approximately forty-five decimeters:

450 cm ≅ 45 dm

An alternative is also that one decimeter is approximately zero point zero two two times four hundred fifty centimeters.
