scene scale with cloth simulation


I am starting experiments with cloth simulation and i am wondering how the scene scale is considered or how to define it. A piece of cloth that is 10 meters tall will not behave the same as a 1 meter tall one… What is the default scene scale and how can we alter it so a blender unit becomes 2 meters instead of one for example.

Thank you !

For physics sims, 1 Blender unit is equal to 1 meter when your object scale is 1. Just model things to this scale.
