Conversion formula

The conversion factor from decimeters to meters is 0.1, which means that 1 decimeter is equal to 0.1 meters:

1 dm = 0.1 m

To convert 45 decimeters into meters we have to multiply 45 by the conversion factor in order to get the length amount from decimeters to meters. We can also form a simple proportion to calculate the result:

1 dm → 0.1 m

45 dm → L_(m)

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

L_(m) = 45 dm × 0.1 m

L_(m) = 4.5 m

The final result is:

45 dm → 4.5 m

We conclude that 45 decimeters is equivalent to 4.5 meters:

45 decimeters = 4.5 meters

Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case 1 meter is equal to 0.22222222222222 × 45 decimeters.

Another way is saying that 45 decimeters is equal to 1 ÷ 0.22222222222222 meters.

Approximate result

For practical purposes we can round our final result to an approximate numerical value. We can say that forty-five decimeters is approximately four point five meters:

45 dm ≅ 4.5 m

An alternative is also that one meter is approximately zero point two two two times forty-five decimeters.
