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 580 millimeters into decimeters we have to multiply 580 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

580 mm → L_(dm)

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

L_(dm) = 580 mm × 0.01 dm

L_(dm) = 5.8 dm

The final result is:

580 mm → 5.8 dm

We conclude that 580 millimeters is equivalent to 5.8 decimeters:

580 millimeters = 5.8 decimeters

Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case 1 decimeter is equal to 0.17241379310345 × 580 millimeters.

Another way is saying that 580 millimeters is equal to 1 ÷ 0.17241379310345 decimeters.

Approximate result

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

580 mm ≅ 5.8 dm

An alternative is also that one decimeter is approximately zero point one seven two times five hundred eighty millimeters.
