Conversion formula
How to convert 510 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}{510 dm} = \frac{0.0001 km}{x km}

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

x km = \frac{510 dm}{1 dm} * 0.0001 km \to x km = 0.051000000000000004 km

Conclusion: $510 dm = 0.051000000000000004 km$

510 decimeters is equivalent to 0.051 kilometers
