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 1004.2 millimeters into decimeters we have to multiply 1004.2 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

1004.2 mm → L_(dm)

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

L_(dm) = 1004.2 mm × 0.01 dm

L_(dm) = 10.042 dm

The final result is:

1004.2 mm → 10.042 dm

We conclude that 1004.2 millimeters is equivalent to 10.042 decimeters:

1004.2 millimeters = 10.042 decimeters

Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case 1 decimeter is equal to 0.099581756622187 × 1004.2 millimeters.

Another way is saying that 1004.2 millimeters is equal to 1 ÷ 0.099581756622187 decimeters.

Approximate result

For practical purposes we can round our final result to an approximate numerical value. We can say that one thousand four point two millimeters is approximately ten point zero four two decimeters:

1004.2 mm ≅ 10.042 dm

An alternative is also that one decimeter is approximately zero point one times one thousand four point two millimeters.
