Conversion formula

The conversion factor from millimeters to decimeters is 0.01, which means that 1 millimeter is equal to 0.01 decimeters:

1 mm = 0.01 dm

To convert 230 millimeters into decimeters we have to multiply 230 by the conversion factor in order to get the length amount from millimeters to decimeters. We can also form a simple proportion to calculate the result:

1 mm → 0.01 dm

230 mm → L_(dm)

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

L_(dm) = 230 mm × 0.01 dm

L_(dm) = 2.3 dm

The final result is:

230 mm → 2.3 dm

We conclude that 230 millimeters is equivalent to 2.3 decimeters:

230 millimeters = 2.3 decimeters

Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case 1 decimeter is equal to 0.43478260869565 × 230 millimeters.

Another way is saying that 230 millimeters is equal to 1 ÷ 0.43478260869565 decimeters.

Approximate result

For practical purposes we can round our final result to an approximate numerical value. We can say that two hundred thirty millimeters is approximately two point three decimeters:

230 mm ≅ 2.3 dm

An alternative is also that one decimeter is approximately zero point four three five times two hundred thirty millimeters.
