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 48.9 inches into decimeters we have to multiply 48.9 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

48.9 in → L_(dm)

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

L_(dm) = 48.9 in × 0.254 dm

L_(dm) = 12.4206 dm

The final result is:

48.9 in → 12.4206 dm

We conclude that 48.9 inches is equivalent to 12.4206 decimeters:
