Units very small?

Hi, 
Not sure if this counts as a bug or it's just me..  I noticed that velocity values seem to be very sensitive.
I'm using centimeters and most of the time I have to dial down values a lot to get ok speeds. 
I haven't really done extensive testing on this, just posting this here to remind myself to check....

It all depends on your scene scale. Forces are calculated in generic units, but displayed in whatever unit type you've chosen. If your scene scale is small, then force values will have to stay small to compensate.
