## Conversion formula

How to convert 686 decimeters to meters?

We know (by definition) that: $1\mathrm{dm}=0.1\mathrm{m}$

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

$\frac{1\mathrm{dm}}{686\mathrm{dm}}=\frac{0.1\mathrm{m}}{x\mathrm{m}}$Now, we cross multiply to solve for our unknown $x$:

$x\mathrm{m}=\frac{686\mathrm{dm}}{1\mathrm{dm}}*0.1\mathrm{m}\to x\mathrm{m}=68.60000000000001\mathrm{m}$Conclusion: $686\mathrm{dm}=68.60000000000001\mathrm{m}$
