## 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 46 decimeters into millimeters we have to multiply 46 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

46 dm → L(mm)

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

L(mm) = 46 dm × 100 mm

L(mm) = 4600 mm

The final result is:

46 dm → 4600 mm

We conclude that 46 decimeters is equivalent to 4600 millimeters:

46 decimeters = 4600 millimeters

## Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case 1 millimeter is equal to 0.00021739130434783 × 46 decimeters.

Another way is saying that 46 decimeters is equal to 1 ÷ 0.00021739130434783 millimeters.

## Approximate result

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

46 dm ≅ 4600 mm

An alternative is also that one millimeter is approximately zero times forty-six decimeters.
