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 34.2 millimeters into decimeters we have to multiply 34.2 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

34.2 mm → L(dm)

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

L(dm) = 34.2 mm × 0.01 dm

L(dm) = 0.342 dm

The final result is:

34.2 mm → 0.342 dm

We conclude that 34.2 millimeters is equivalent to 0.342 decimeters:

34.2 millimeters = 0.342 decimeters
