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 850 millimeters into decimeters we have to multiply 850 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

850 mm → L_(dm)

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

L_(dm) = 850 mm × 0.01 dm

L_(dm) = 8.5 dm

The final result is:

850 mm → 8.5 dm

We conclude that 850 millimeters is equivalent to 8.5 decimeters:

850 millimeters = 8.5 decimeters

Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case 1 decimeter is equal to 0.11764705882353 × 850 millimeters.

Another way is saying that 850 millimeters is equal to 1 ÷ 0.11764705882353 decimeters.

Approximate result

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

850 mm ≅ 8.5 dm

An alternative is also that one decimeter is approximately zero point one one eight times eight hundred fifty millimeters.
