## 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 38 decimeters into millimeters we have to multiply 38 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

38 dm → L(mm)

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

L(mm) = 38 dm × 100 mm

L(mm) = 3800 mm

The final result is:

38 dm → 3800 mm

We conclude that 38 decimeters is equivalent to 3800 millimeters:

38 decimeters = 3800 millimeters

## Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case 1 millimeter is equal to 0.00026315789473684 × 38 decimeters.

Another way is saying that 38 decimeters is equal to 1 ÷ 0.00026315789473684 millimeters.

## Approximate result

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

38 dm ≅ 3800 mm

An alternative is also that one millimeter is approximately zero times thirty-eight decimeters.
