Conversion formula

The conversion factor from decimeters to millimeters is 100, which means that 1 decimeter is equal to 100 millimeters:

1 dm = 100 mm

To convert 3423 decimeters into millimeters we have to multiply 3423 by the conversion factor in order to get the length amount from decimeters to millimeters. We can also form a simple proportion to calculate the result:

1 dm → 100 mm

3423 dm → L(mm)

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

L(mm) = 3423 dm × 100 mm

L(mm) = 342300 mm

The final result is:

3423 dm → 342300 mm

We conclude that 3423 decimeters is equivalent to 342300 millimeters:

3423 decimeters = 342300 millimeters
