try it!, make a cube in Maya/Cart4 40x40x40, import it and then use the object size(objectnumber) function to see what size it is, a lot of media seems to follow the 1 unit to a meter rule, but as was said, it`s not hard and fast.

here`s the code if you need it
sync on: sync rate 60
load object "objectname.x",1
do
text 200,200,"object is :"+str$(object size(1))+": in size"
sync
loop
