## 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 37.8 decimeters into millimeters we have to multiply 37.8 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

37.8 dm → L_{(mm)}

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

L_{(mm)} = 37.8 dm × 100 mm

L_{(mm)} = 3780 mm

The final result is:

37.8 dm → 3780 mm
