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 15.5 decimeters into millimeters we have to multiply 15.5 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

15.5 dm → L(mm)

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

L(mm) = 15.5 dm × 100 mm

L(mm) = 1550 mm

The final result is:

15.5 dm → 1550 mm

We conclude that 15.5 decimeters is equivalent to 1550 millimeters:

15.5 decimeters = 1550 millimeters

Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case 1 millimeter is equal to 0.00064516129032258 × 15.5 decimeters.

Another way is saying that 15.5 decimeters is equal to 1 ÷ 0.00064516129032258 millimeters.

Approximate result

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

15.5 dm ≅ 1550 mm

An alternative is also that one millimeter is approximately zero point zero zero one times fifteen point five decimeters.
