The grid size is auto, determined by the zooming scale.

For example, grid is set to by a number 10, based on the current zooming. Setting units gives the number 10 units:

Setting units to mm, means the grid is currently by 10mm. When setting units to inch, it means the grid is currently by 10 inch.
