## 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 4 inches into decimeters we have to multiply 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

4 in → L(dm)

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

L(dm) = 4 in × 0.254 dm

L(dm) = 1.016 dm

The final result is:

4 in → 1.016 dm

We conclude that 4 inches is equivalent to 1.016 decimeters:

4 inches = 1.016 decimeters
