Simple methods for converting equations between the SI, Heaviside-Lorentz and Gaussian systems
Paul Quincey
School and undergraduate students are almost always taught the equations of electromagnetism using a set of conventions that are described as the SI. More advanced students are oft…
Angles in the SI: a detailed proposal for solving the problem
Paul Quincey
A recent Letter proposed changing the dimensionless status of the radian and steradian within the SI, while allowing the continued use of the convention to set the angle 1 radian e…
Solid angles in perspective
Paul Quincey
The specialised uses of solid angles mean that they are quite unfamiliar quantities. This article, apart from making solid angles a little more familiar, brings out several topics…
Angles in the SI: treating the radian as an independent, unhidden unit does not require the redefinition of the term frequency or the unit hertz
Paul Quincey
Some recent papers have argued that frequency should have the dimensions of angle/time, with the consequences that 1 Hz = rad/s instead of 1 s, and also that and…
The role of unit systems in expressing and testing the laws of nature
Paul Quincey, Kathryn Burrows
The paper firstly argues from conservation principles that, when dealing with physics aside from elementary particle interactions, the number of naturally independent quantities, a…
Angles are inherently neither length ratios nor dimensionless
Paul Quincey, Peter J Mohr, William D Phillips
The status of angles within The International System of Units (SI) has long been a source of controversy and confusion. We address one specific but crucial issue, putting the case…
A clearer approach for defining unit systems
Paul Quincey, Richard J. C. Brown
We present the SI and other unit systems, including cgs-em and cgs-es, in a framework whereby a system of fully independent and dimensionally orthogonal base units is modified by c…
Implications of adopting plane angle as a base quantity in the SI
Paul Quincey, Richard J C Brown
The treatment of angles within the SI is anomalous compared with other quantities, and there is a case for removing this anomaly by declaring plane angle to be an additional base q…
Comment on Dimensionless Units in the SI
Paul Quincey
The recent paper by Mohr and Phillips (arXiv:1409.2794) describes several problems relating to the treatment of angle measurement within SI, the unit hertz, and quantities that can…
