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 6380 decimeters into millimeters we have to multiply 6380 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

6380 dm → L_(mm)

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

L_(mm) = 6380 dm × 100 mm

L_(mm) = 638000 mm

The final result is:

6380 dm → 638000 mm
