removed subclass-of magnitude[edit]
it was redundant because a physical property is already a magnitude by being a quantity which is a scalar which is a magnitude DavRosen (talk) 19:57, 26 January 2017 (UTC)
This class has a lot of (indirect) subclasses which are not physical quantities[edit]
Look at that discussion. One great error is introduced by defining the time (Q11471) as a subclass of physical quantity (Q107715). It is the time-interval which is a measurable quantity. Further unit of time (Q1790144) should not be a subclass of time interval (Q186081), better use the statement unit of time (Q1790144) instance of (P31) time interval (Q186081). In the main objects that have properties which are physical quantity (Q107715) should not be subclasses of physical quantity (Q107715).
