Conversion formula

The conversion factor from millimeters to decimeters is 0.01, which means that 1 millimeter is equal to 0.01 decimeters:

1 mm = 0.01 dm

To convert 38 millimeters into decimeters we have to multiply 38 by the conversion factor in order to get the length amount from millimeters to decimeters. We can also form a simple proportion to calculate the result:

1 mm → 0.01 dm

38 mm → L_(dm)

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

L_(dm) = 38 mm × 0.01 dm

L_(dm) = 0.38 dm

The final result is:

38 mm → 0.38 dm

We conclude that 38 millimeters is equivalent to 0.38 decimeters:

38 millimeters = 0.38 decimeters

Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case 1 decimeter is equal to 2.6315789473684 × 38 millimeters.

Another way is saying that 38 millimeters is equal to 1 ÷ 2.6315789473684 decimeters.

Approximate result

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

38 mm ≅ 0.38 dm

An alternative is also that one decimeter is approximately two point six three two times thirty-eight millimeters.
