The dimension of Intensity is, as the unit W/m^2 suggests, L^2 M T^-3 / L^2 = M T^-3. Majortom777 ( talk) 21:51, 6 June 2016 (UTC)
The symbol for velocity is "v", not "V". UED77 22:21, 2004 Sep 12 (UTC)
Why not remove the SI-Units (since this is a list of physical quantities and not physical units) and use some more space on information regarding vector/scalar and intrinsic/extrinsic property, etc.?
Question: Doesn't velocity require a vector, while speed does not?
It would be nice to let the reader what [M], [L], [T],... stand for. Headbomb { ταλκ – WP Physics: PotW} 13:03, 25 July 2008 (UTC)
I know it's dimensionless, but it should definitely be up here.-- ArtifexCrastinus ( talk) 07:31, 8 September 2008 (UTC)
Shouldn't there be something in the introduction about using symbols in such places as custom equations and column headings. I've often seen them with subscripts to right of them indicating the substance of which they describe. For example, the mass of a lead object can be represented as mPb. Is this not as common as I thought? -- ArtifexCrastinus ( talk) 07:43, 8 September 2008 (UTC)
Current is not a base quantity, charge (Coulombs) is. (Current is Charge / time). MysticMetal ( talk) 09:19, 21 September 2010 (UTC)
Should we add a sortable column that says what it's generally used for (Chemistry, Electricity/magnetism, Physics), so if someone's interested in Electrical properties, they can sort based on that column (I came upon this page wondering about physical quantities...)? MysticMetal ( talk) 09:22, 21 September 2010 (UTC)
Should we have it generally sorted so chemical properties are before (<) electrical < physical < magnetic? So far it's just cobbled together... -- MysticMetal ( talk) 09:27, 21 September 2010 (UTC)
The articles defining equation (physics) and defining equation (physical chemistry) are essentially the same with formulae, units, and dimensions in excruciating detail but they lack the 1-phrase explanation style given in this article. What do people think of splitting and transferring content from this article into those? Maschen ( talk) 08:00, 5 September 2012 (UTC)
I would agree. Njaohnt ( talk) 17:53, 3 November 2012 (UTC)
Since there is an international standard system of physical quantities ( ISO/IEC 80000) why isn't this list page based on it? D.keenan ( talk) 02:46, 11 May 2017 (UTC)
Plane Angle and Solid Angle were previously listed in the Base Quantities list. But now they are in Derived quantities list. I think they should be listed in the Base Quantities list. Che12PM 13:51, 6 June 2017 (UTC)
NIST (at [ [1]]) considers bytes/MB/GB/etc. to be SI units; a whole special system of binary prefixes has been created by IEC.
So, is information / data storage measured in a base quantity, or as a population (like people or moles) based on the base quantity "amount"? Casu Marzu ( talk) 19:58, 8 June 2017 (UTC)
Adding the simplest formula of the physical quantity will make the dimension essey. If you will aggery my suggestion ,it must be better for it. Padmanabha Dhala ( talk) 05:00, 29 June 2019 (UTC)
how about explaining GM/c2 as a usual astrophysical unit (in the theory of black holes) including "G"? thanx! HilmarHansWerner ( talk) 12:49, 17 February 2021 (UTC)
