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 4.7 decimeters into millimeters we have to multiply 4.7 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

4.7 dm → L_(mm)

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

L_(mm) = 4.7 dm × 100 mm

L_(mm) = 470 mm

The final result is:

4.7 dm → 470 mm

We conclude that 4.7 decimeters is equivalent to 470 millimeters:

4.7 decimeters = 470 millimeters

Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case 1 millimeter is equal to 0.0021276595744681 × 4.7 decimeters.

Another way is saying that 4.7 decimeters is equal to 1 ÷ 0.0021276595744681 millimeters.

Approximate result

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

4.7 dm ≅ 470 mm

An alternative is also that one millimeter is approximately zero point zero zero two times four point seven decimeters.
