Dimensions of physical quantities

[QUOTE="Bandersnatch, post: 4944168, member: 399360"] Right, you can see it used that way sometimes. You can also see for example "length" being called "units" of position (x). Or dimension being called quantity. The important bit is to keep it consistent across the board, so that you don't mix something like "length" and "kilograms", or "mass" and "Kelvins" in your analysis. Sticking to unitless dimensions should be prioritised, though, as it let's you analyse whatever equation you're analysing without bothering with what particular system of units you ought to use (i.e., metric, cgs, imperial etc.). Anyway, this is a nice tutorial on dimensional analysis: [url]http://vallance.chem.ox.ac.uk/pdfs/UnitsAndDimensions.pdf[/url] Give it a read if you get confused again. [/QUOTE]
