## 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 16.7 decimeters into millimeters we have to multiply 16.7 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

16.7 dm → L(mm)

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

L(mm) = 16.7 dm × 100 mm

L(mm) = 1670 mm

The final result is:

16.7 dm → 1670 mm

We conclude that 16.7 decimeters is equivalent to 1670 millimeters:

16.7 decimeters = 1670 millimeters

## Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case 1 millimeter is equal to 0.00059880239520958 × 16.7 decimeters.

Another way is saying that 16.7 decimeters is equal to 1 ÷ 0.00059880239520958 millimeters.

## Approximate result

For practical purposes we can round our final result to an approximate numerical value. We can say that sixteen point seven decimeters is approximately one thousand six hundred seventy millimeters:

16.7 dm ≅ 1670 mm

An alternative is also that one millimeter is approximately zero point zero zero one times sixteen point seven decimeters.
