## 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 85 decimeters into millimeters we have to multiply 85 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

85 dm → L(mm)

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

L(mm) = 85 dm × 100 mm

L(mm) = 8500 mm

The final result is:

85 dm → 8500 mm

We conclude that 85 decimeters is equivalent to 8500 millimeters:

85 decimeters = 8500 millimeters

## Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case 1 millimeter is equal to 0.00011764705882353 × 85 decimeters.
