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 1422 decimeters into millimeters we have to multiply 1422 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

1422 dm → L_(mm)

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

L_(mm) = 1422 dm × 100 mm

L_(mm) = 142200 mm

The final result is:

1422 dm → 142200 mm

We conclude that 1422 decimeters is equivalent to 142200 millimeters:

1422 decimeters = 142200 millimeters
