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 457 decimeters into millimeters we have to multiply 457 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

457 dm → L(mm)

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

L(mm) = 457 dm × 100 mm

L(mm) = 45700 mm

The final result is:

457 dm → 45700 mm
