Abstract
This letter considers the potential for confusion in the presentation and interpretation of measurement results caused by the existence of upper- and lower-case letter pairs for SI prefix symbols, an example of this being the newest prefix symbols Q & q and R & r, adopted at the 27th Meeting of the General Conference on Weights and Measures in November 2022. The requirements of digitalisation and machine readability, when making choices for new unit and prefix symbols, are also examined.
期刊介绍：
Published 6 times per year, Metrologia covers the fundamentals of measurements, particularly those dealing with the seven base units of the International System of Units (metre, kilogram, second, ampere, kelvin, candela, mole) or proposals to replace them.
The journal also publishes papers that contribute to the solution of difficult measurement problems and improve the accuracy of derived units and constants that are of fundamental importance to physics.
In addition to regular papers, the journal publishes review articles, issues devoted to single topics of timely interest and occasional conference proceedings. Letters to the Editor and Short Communications (generally three pages or less) are also considered.
