Conversion formula
How to convert 3 decimeters to meters?

We know (by definition) that: 1 dm = 0.1 m.

We can set up a proportion to solve for the number of meters.

1 dm / 3 dm = 0.1 m / x m

Now, we cross multiply to solve for our unknown x:

x m = (3 dm / 1 dm) * 0.1 m → x m = 0.30000000000000004 m

Conclusion:

3 dm = 0.30000000000000004 m

Conversion in the opposite direction

The inverse of the conversion factor is that 1 meter is equal to 3.33333333333333 times 3 decimeters.

It can also be expressed as: 3 decimeters is equal to 1 / 3.33333333333333 meters.

Approximation

An approximate numerical result would be: three decimeters is about zero meters, or alternatively, a meter is about three point three three times three decimeters.
