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 304 millimeters into decimeters we have to multiply 304 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

304 mm → L_(dm)

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

L_(dm) = 304 mm × 0.01 dm

L_(dm) = 3.04 dm

The final result is:

304 mm → 3.04 dm

We conclude that 304 millimeters is equivalent to 3.04 decimeters:

304 millimeters = 3.04 decimeters

Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case 1 decimeter is equal to 0.32894736842105 × 304 millimeters.

Another way is saying that 304 millimeters is equal to 1 ÷ 0.32894736842105 decimeters.

Approximate result

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

304 mm ≅ 3.04 dm

An alternative is also that one decimeter is approximately zero point three two nine times three hundred four millimeters.
