## 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 173 decimeters into millimeters we have to multiply 173 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

173 dm → L(mm)

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

L(mm) = 173 dm × 100 mm

L(mm) = 17300 mm

The final result is:

173 dm → 17300 mm

We conclude that 173 decimeters is equivalent to 17300 millimeters:

173 decimeters = 17300 millimeters

## Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case 1 millimeter is equal to 5.7803468208092E-5 × 173 decimeters.

Another way is saying that 173 decimeters is equal to 1 ÷ 5.7803468208092E-5 millimeters.

## Approximate result

For practical purposes we can round our final result to an approximate numerical value. We can say that one hundred seventy-three decimeters is approximately seventeen thousand three hundred millimeters:

173 dm ≅ 17300 mm

An alternative is also that one millimeter is approximately zero times one hundred seventy-three decimeters.
