Angles in the SI: a detailed proposal for solving the problem

  title={Angles in the SI: a detailed proposal for solving the problem},
  author={Paul Quincey},
A recent letter [1] 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 equal to the number 1 within equations, providing this is done explicitly. This would bring the advantages of a physics-based, consistent, and logically-robust unit system, with unambiguous units for all physical quantities, for the first time, while any upheaval to familiar equations and routine practice would be… 
Comment on ‘Angles in the SI: a detailed proposal for solving the problem’
Paul Quincey makes a compelling argument for recognizing angle as a base quantity with the radian as the base unit. Solid angle is then a derived quantity with the steradian a coherent derived unit
Reply to Comment on ‘Angles in the SI: a detailed proposal for solving the problem’
The comment by Leonard (2022 Metrologia 59 038001) primarily proposes that if angle is treated as a base quantity, with the radian as its base unit, it would be wrong to change the units for torque
On the dimension of angles and their units
We show the implications of angles having their own dimension, which facilitates a consistent use of units as is done for lengths, masses, and other physical quantities. We do this by examining the


Implications of adopting plane angle as a base quantity in the SI
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 quantity within the
Proposal for the dimensionally consistent treatment of angle and solid angle by the International System of Units (SI)
Because of continued confusion caused by the SI’s interpretation of angle and solid angle as dimensionless quantities (and the radian and steradian as dimensionless derived units), it is time for the
The role of unit systems in expressing and testing the laws of nature
The paper firstly argues from conservation principles that, when dealing with physics aside from elementary particle interactions, the number of naturally independent quantities, and hence the
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
Some recent papers have argued that frequency should have the dimensions of angle/time, with the consequences that 1 Hz = 2π rad s−1 instead of 1 s−1, and also that ν = ω and h = ħ. This letter puts
Angles-Let's treat them squarely
We suggest a self-consistent treatment of the dimensions and units of the geometric quantity “angle.” The method regards “angle” as a fundamental dimensional physical quantity, on a par with length,
Solid angles in perspective
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 of general
On Angles and Angular Quantities
It is argued that angles are geometric quantities and have a dimension. The equation giving the length s of the arc cut out by an angle on a circle of radius R is written as s = ? R , where ? is a
Dimensionless units in the SI
The International System of Units (SI) is supposed to be coherent. That is, when a combination of units is replaced by an equivalent unit, there is no additional numerical factor. Here we consider
On the status of plane and solid angles in the International System of Units (SI)
The article analyzes the arguments that have become the basis for the 1980 CIPM recommendations declaring plane and solid angles as dimensionless derived quantities. This decision was the result of
Indian Values of the Sinus Totus
The predecessor of the modern trigonometric function known as the sine of an angle was born, apparently, in India. The Greek trigonometry had been based on the functional relationship between the
