Conversion formula

The conversion factor from decimeters to centimeters is 10, which means that 1 decimeter is equal to 10 centimeters:

1 dm = 10 cm

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

1 dm → 10 cm

45 dm → L_(cm)

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

L_(cm) = 45 dm × 10 cm

L_(cm) = 450 cm

The final result is:

45 dm → 450 cm

We conclude that 45 decimeters is equivalent to 450 centimeters:

45 decimeters = 450 centimeters

Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case 1 centimeter is equal to 0.0022222222222222 × 45 decimeters.

Another way is saying that 45 decimeters is equal to 1 ÷ 0.0022222222222222 centimeters.

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 hundred fifty centimeters:

45 dm ≅ 450 cm

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