## 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 3.4 inches into decimeters we have to multiply 3.4 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

3.4 in → L(dm)

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

L(dm) = 3.4 in × 0.254 dm

L(dm) = 0.8636 dm

The final result is:

3.4 in → 0.8636 dm

We conclude that 3.4 inches is equivalent to 0.8636 decimeters:

3.4 inches = 0.8636 decimeters
