## 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 1.5 inches into decimeters we have to multiply 1.5 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

1.5 in → L(dm)

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

L(dm) = 1.5 in × 0.254 dm

L(dm) = 0.381 dm

The final result is:

1.5 in → 0.381 dm

We conclude that 1.5 inches is equivalent to 0.381 decimeters:

1.5 inches = 0.381 decimeters

## Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case 1 decimeter is equal to 2.6246719160105 × 1.5 inches.

Another way is saying that 1.5 inches is equal to 1 ÷ 2.6246719160105 decimeters.

## Approximate result

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

1.5 in ≅ 0.381 dm

An alternative is also that one decimeter is approximately two point six two five times one point five inches.
