I'm not sure a dust storm on Mars poses much risk to someone on the
surface. The dust grains themselves could be abrasive and do some
surface damage to a suit, but otherwise, you'd hardly notice the
fastest winds on Mars, which have less energy than a mild breeze on
Earth.

That's an interesting point.

Conversely, the slightest breeze on Venus is equivalent to a hurricane on Earth.


Although you'd probably not be worrying about the force of the wind so
much as the fact that it consisted of 800° sulfuric acid!


Fahrenheit?
Hang your head in shame.


Not that the units really matter at that point. 800 has a nice ring to
it. But if you prefer, we could go with 800 K, which is pretty close
to the mark.
