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 5280 decimeters into millimeters we have to multiply 5280 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

5280 dm → L_(mm)

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

L_(mm) = 5280 dm × 100 mm

L_(mm) = 528000 mm

The final result is:

5280 dm → 528000 mm

We conclude that 5280 decimeters is equivalent to 528000 millimeters:

5280 decimeters = 528000 millimeters
