## 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 120 inches into decimeters we have to multiply 120 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

120 in → L(dm)

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

L(dm) = 120 in × 0.254 dm

L(dm) = 30.48 dm

The final result is:

120 in → 30.48 dm

We conclude that 120 inches is equivalent to 30.48 decimeters:

120 inches = 30.48 decimeters

## Alternative conversion
