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 622 decimeters into millimeters we have to multiply 622 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

622 dm → L_(mm)

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

L_(mm) = 622 dm × 100 mm

L_(mm) = 62200 mm

The final result is:

622 dm → 62200 mm

We conclude that 622 decimeters is equivalent to 62200 millimeters:

622 decimeters = 62200 millimeters
