The conversion factor from feet to decimeters is 3.048, which means that 1 foot is equal to 3.048 decimeters:
1 ft = 3.048 dm
To convert 138 feet into decimeters we have to multiply 138 by the conversion factor in order to get the length amount from feet to decimeters. We can also form a simple proportion to calculate the result:
1 ft → 3.048 dm
138 ft → L(dm)
Solve the above proportion to obtain the length L in decimeters:
L(dm) = 138 ft × 3.048 dm
L(dm) = 420.624 dm
The final result is:
138 ft → 420.624 dm
We conclude that 138 feet is equivalent to 420.624 decimeters:
