## Conversion formula

The conversion factor from inches to decimeters is 0.254, which means that 1 inch is equal to 0.254 decimeters:

1 in = 0.254 dm

To convert 0.9 inches into decimeters we have to multiply 0.9 by the conversion factor in order to get the length amount from inches to decimeters. We can also form a simple proportion to calculate the result:

1 in → 0.254 dm

0.9 in → L(dm)

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

L(dm) = 0.9 in × 0.254 dm

L(dm) = 0.2286 dm

The final result is:

0.9 in → 0.2286 dm

We conclude that 0.9 inches is equivalent to 0.2286 decimeters:

0.9 inches = 0.2286 decimeters

## Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case 1 decimeter is equal to 4.3744531933508 × 0.9 inches.

Another way is saying that 0.9 inches is equal to 1 ÷ 4.3744531933508 decimeters.

## Approximate result

For practical purposes we can round our final result to an approximate numerical value. We can say that zero point nine inches is approximately zero point two two nine decimeters:

0.9 in ≅ 0.229 dm

An alternative is also that one decimeter is approximately four point three seven four times zero point nine inches.
