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 80 inches into decimeters we have to multiply 80 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

80 in → L_(dm)

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

L_(dm) = 80 in × 0.254 dm

L_(dm) = 20.32 dm

The final result is:

80 in → 20.32 dm

We conclude that 80 inches is equivalent to 20.32 decimeters:
