Microsoft Visio can handle many different units of measurements which can be set for a page and separately for shapes, such as dimensions, within the page. This can confuse some users who expect them both to be the same all the time. In fact, the dimension units can be set to be the same as the page units, but not necessarily so. It is possible to have different units on different dimension shapes, but is also possible to set all the same with one click, and to synchronise them with the page units.
