## 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 340 centimeters into decimeters we have to multiply 340 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

340 cm → L(dm)

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

L(dm) = 340 cm × 0.1 dm

L(dm) = 34 dm

The final result is:

340 cm → 34 dm

We conclude that 340 centimeters is equivalent to 34 decimeters:

340 centimeters = 34 decimeters

## Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case 1 decimeter is equal to 0.029411764705882 × 340 centimeters.

Another way is saying that 340 centimeters is equal to 1 ÷ 0.029411764705882 decimeters.

## Approximate result

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

340 cm ≅ 34 dm

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