Conversion

340 kilometers is equivalent to 340000000 millimeters.[1]

Conversion formula How to convert 340 kilometers to millimeters?

We know (by definition) that: $1\mathrm{km}=1000000\mathrm{mm}$

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

$1 ⁢ km 340 ⁢ km = 1000000 ⁢ mm x ⁢ mm$

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

$x\mathrm{mm}=\frac{340\mathrm{km}}{1\mathrm{km}}*1000000\mathrm{mm}\to x\mathrm{mm}=340000000\mathrm{mm}$

Conclusion: $340 ⁢ km = 340000000 ⁢ mm$
