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 42.1 decimeters into millimeters we have to multiply 42.1 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

42.1 dm → L(mm)

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

L(mm) = 42.1 dm × 100 mm

L(mm) = 4210 mm

The final result is:

42.1 dm → 4210 mm

We conclude that 42.1 decimeters is equivalent to 4210 millimeters:

42.1 decimeters = 4210 millimeters
