800 kilometers in decimeters

Conversion formula
How to convert 800 kilometers to decimeters?

We know (by definition) that: $1\mathrm{km}=10000\mathrm{dm}$

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

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

Conclusion: 800 ⁢ km = 8000000 ⁢ dm

Conversion in the opposite direction

The inverse of the conversion factor is that 1 decimeter is equal to 1.25e-07 times 800 kilometers.

It can also be expressed as: 800 kilometers is equal to $\frac{1}{\mathrm{1.25e-07}}$ decimeters.

Approximation

An approximate numerical result would be: eight hundred kilometers is about eight million decimeters, or alternatively, a decimeter is about zero times eight hundred kilometers.
