Conversion formula

The conversion factor from millimeters to decimeters is 0.01, which means that 1 millimeter is equal to 0.01 decimeters:

1 mm = 0.01 dm

To convert 1397 millimeters into decimeters we have to multiply 1397 by the conversion factor in order to get the length amount from millimeters to decimeters. We can also form a simple proportion to calculate the result:

1 mm → 0.01 dm

1397 mm → L_(dm)

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

L_(dm) = 1397 mm × 0.01 dm

L_(dm) = 13.97 dm

The final result is:

1397 mm → 13.97 dm

We conclude that 1397 millimeters is equivalent to 13.97 decimeters:

1397 millimeters = 13.97 decimeters
