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

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

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

The CO2 molecule is never linear



The Planck constant and its units

On the Theory of quantum mechanics

The new mechanics of the atom introduced by Heisenberg may be based on the assumption that the variables that describe a dynamical system do not obey the commutative law of multiplication, but

On the units radian and cycle for the quantity plane angle

This paper is concerned with the names and symbols for quantities used to describe oscillatory motion such as for a harmonic oscillator, and the units to be used for the quantity plane angle and

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

A summary of the Planck constant determinations using the NRC Kibble balance

We present a summary of the Planck constant determinations using the NRC watt balance, now referred to as the NRC Kibble balance. The summary includes a reanalysis of the four determinations

Angles are inherently neither length ratios nor dimensionless

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 that the idea of

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

Data and analysis for the CODATA 2017 special fundamental constants adjustment

The special least-squares adjustment of the values of the fundamental constants, carried out by the Committee on Data for Science and Technology (CODATA) in the summer of 2017, is described in
