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 5170 decimeters into millimeters we have to multiply 5170 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

5170 dm → L_(mm)

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

L_(mm) = 5170 dm × 100 mm

L_(mm) = 517000 mm

The final result is:

5170 dm → 517000 mm
