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 5420 decimeters into millimeters we have to multiply 5420 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

5420 dm → L_(mm)

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

L_(mm) = 5420 dm × 100 mm

L_(mm) = 542000 mm

The final result is:

5420 dm → 542000 mm

We conclude that 5420 decimeters is equivalent to 542000 millimeters:

5420 decimeters = 542000 millimeters
