## 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 1.7 inches into decimeters we have to multiply 1.7 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

1.7 in → L(dm)

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

L(dm) = 1.7 in × 0.254 dm

L(dm) = 0.4318 dm

The final result is:

1.7 in → 0.4318 dm

We conclude that 1.7 inches is equivalent to 0.4318 decimeters:

1.7 inches = 0.4318 decimeters

## Alternative conversion
