units are arbitray

this place designates the distance btween here an there is X

that place designates the distance btween here an there is Y

 

so long as you do the x/y    in your head there shouldnt be more then minor problems

(if you get a major problem move the decimal point ;-) or is that just me )

the 1 can be 1 foot or 1 metre or 1 mile

the 1/10 is one tenth of the unit I want it to be

if my model was 1 lightyear long

1/10 would be roughly 6 light weeks (yes I know but cant accelerate or brake THAT fast lol
