THANKS For YOUR Help and sorry for my not mastered english.

1 = 1 meter

In Unity, there is no definition of a unit. You can call the unit of length in unity whatever you want. You can call it a “unit” if you so wish. 0.1 units could be 1 meter. Or 5 units could be 1 meter.

It doesn’t matter as long as you keep that sort of thing constant. e.g. Don’t go from:

1 units = 1 meter

to

12 units = 1 meter.
