## 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 8 decimeters into millimeters we have to multiply 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

8 dm → L_{(mm)}

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

L_{(mm)} = 8 dm × 100 mm

L_{(mm)} = 800 mm

The final result is:

8 dm → 800 mm

We conclude that **8 decimeters is equivalent to 800 millimeters**:

8 decimeters = 800 millimeters

## Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case **1 millimeter is equal to 0.00125 × 8 decimeters**.

Another way is saying that *8 decimeters is equal to 1 ÷ 0.00125 millimeters*.

## Approximate result

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

8 dm ≅ 800 mm

An alternative is also that *one millimeter is approximately zero point zero zero one times eight decimeters*.
