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.

1 dm / 510 dm = 0.0001 km / x km

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

x km = (510 dm / 1 dm) * 0.0001 km → x km = 0.051000000000000004 km

Conclusion:

510 dm = 0.051000000000000004 km
