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 1100 millimeters into decimeters we have to multiply 1100 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

1100 mm → L_(dm)

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

L_(dm) = 1100 mm × 0.01 dm

L_(dm) = 11 dm

The final result is:

1100 mm → 11 dm

We conclude that 1100 millimeters is equivalent to 11 decimeters:

1100 millimeters = 11 decimeters

Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case 1 decimeter is equal to 0.090909090909091 × 1100 millimeters.

Another way is saying that 1100 millimeters is equal to 1 ÷ 0.090909090909091 decimeters.

Approximate result

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

1100 mm ≅ 11 dm

An alternative is also that one decimeter is approximately zero point zero nine one times one thousand one hundred millimeters.
