## 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 50 decimeters into millimeters we have to multiply 50 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

50 dm → L(mm)

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

L(mm) = 50 dm × 100 mm

L(mm) = 5000 mm

The final result is:

50 dm → 5000 mm

We conclude that 50 decimeters is equivalent to 5000 millimeters:

50 decimeters = 5000 millimeters

## Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case 1 millimeter is equal to 0.0002 × 50 decimeters.

Another way is saying that 50 decimeters is equal to 1 ÷ 0.0002 millimeters.

## Approximate result

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

50 dm ≅ 5000 mm

An alternative is also that one millimeter is approximately zero times fifty decimeters.
