# 280 decimeters in kilometers

## Conversion

280 decimeters is equivalent to 0.028 kilometers.[1]

## Conversion formula How to convert 280 decimeters to kilometers?

We know (by definition) that: $1\mathrm{dm}=0.0001\mathrm{km}$

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

$1 ⁢ dm 280 ⁢ dm = 0.0001 ⁢ km x ⁢ km$

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

$x\mathrm{km}=\frac{280\mathrm{dm}}{1\mathrm{dm}}*0.0001\mathrm{km}\to x\mathrm{km}=0.028\mathrm{km}$

Conclusion: $280 ⁢ dm = 0.028 ⁢ km$
