Conversion formula

The conversion factor from centimeters to decimeters is 0.1, which means that 1 centimeter is equal to 0.1 decimeters:

1 cm = 0.1 dm

To convert 42 centimeters into decimeters we have to multiply 42 by the conversion factor in order to get the length amount from centimeters to decimeters. We can also form a simple proportion to calculate the result:

1 cm → 0.1 dm

42 cm → L(dm)

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

L(dm) = 42 cm × 0.1 dm

L(dm) = 4.2 dm

The final result is:

42 cm → 4.2 dm

We conclude that 42 centimeters is equivalent to 4.2 decimeters:

42 centimeters = 4.2 decimeters

Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case 1 decimeter is equal to 0.23809523809524 × 42 centimeters.

Another way is saying that 42 centimeters is equal to 1 ÷ 0.23809523809524 decimeters.

Approximate result

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

42 cm ≅ 4.2 dm

An alternative is also that one decimeter is approximately zero point two three eight times forty-two centimeters.
