Conversion formula
How to convert 312 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 / 312 dm = 0.0001 km / x km

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

x km = (312 dm / 1 dm) * 0.0001 km → x km = 0.031200000000000002 km

Conclusion:

312 dm = 0.031200000000000002 km

Conversion in the opposite direction
