Conversion formula
How to convert 511 decimeters to kilometers?

We know (by definition) that: $1 dm = 0.0001 km$

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

\frac{1 dm}{511 dm} = \frac{0.0001 km}{x km}

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

x km = \frac{511 dm}{1 dm} * 0.0001 km \to x km = 0.0511 km

Conclusion: $511 dm = 0.0511 km$

511 decimeters is equivalent to 0.0511 kilometers
