Conversion formula

The conversion factor from millimeters to decimeters is 0.01, which means that 1 millimeter is equal to 0.01 decimeters:

1 mm = 0.01 dm

To convert 8.5 millimeters into decimeters we have to multiply 8.5 by the conversion factor in order to get the length amount from millimeters to decimeters. We can also form a simple proportion to calculate the result:

1 mm → 0.01 dm

8.5 mm → L_(dm)

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

L_(dm) = 8.5 mm × 0.01 dm

L_(dm) = 0.085 dm

The final result is:

8.5 mm → 0.085 dm

We conclude that 8.5 millimeters is equivalent to 0.085 decimeters:

8.5 millimeters = 0.085 decimeters

Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case 1 decimeter is equal to 11.764705882353 × 8.5 millimeters.

Another way is saying that 8.5 millimeters is equal to 1 ÷ 11.764705882353 decimeters.

Approximate result

For practical purposes we can round our final result to an approximate numerical value. We can say that eight point five millimeters is approximately zero point zero eight five decimeters:

8.5 mm ≅ 0.085 dm

An alternative is also that one decimeter is approximately eleven point seven six five times eight point five millimeters.
