## 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 380 decimeters into millimeters we have to multiply 380 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

380 dm → L_{(mm)}

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

L_{(mm)} = 380 dm × 100 mm

L_{(mm)} = 38000 mm

The final result is:

380 dm → 38000 mm

We conclude that **380 decimeters is equivalent to 38000 millimeters**:

380 decimeters = 38000 millimeters

## Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case **1 millimeter is equal to 2.6315789473684E-5 × 380 decimeters**.
